Palestinian militant group Hamas has announced that its leader in Lebanon has been killed by Israeli air strikes as hundreds of IDF tanks line up along the border.
Now fears are mounting about a potential ground invasion by Israel that could plunge the Middle East into an all-out war - as it was revealed 1 million people in Lebanon have now been displaced from their homes.
Hamas said its leader in Lebanon, Fateh Sherif Abu al-Amine, died today in a strike on the Al-Buss refugee camp in the southern city of Tyre - days after Hezbollah's long-standing chief Hassan Nasrallah was killed in Beirut.
The group said al-Amine was killed with his wife, son and daughter in what it called a 'terrorist and criminal assassination'.
That statement came hours after the Popular Front for the Liberation of Palestine (PFLP), a secular left-wing group, said three of its members were killed in a strike on Beirut's Kola district early today.
Most of Israel's attacks against Hezbollah have so far been carried out in the south of Lebanon or Beirut's southern suburbs.
But this morning's attack in the Kola district was the first within Beirut's city limits - another escalation that observers fear could could trigger a wider war, dragging in Iran and the United States.
Meanwhile, the US and other members of the international community this weekend issued an 11th-hour appeal for restraint.
President Joe Biden warned Israeli Prime Minister Benjamin Netanyahu that an all-out war in the Middle East must be avoided, even as the US military ramps up its presence in the region.
More than 1,030 people - including 156 women and 87 children - have been killed in less than two weeks, according to Lebanon's Health Ministry, since Israel stepped up its attacks on Hezbollah.
The airstrike in the Kola district hit a multistory residential building and caused massive damage.
Shocking pictures and videos showed ambulances and fire crews gathered outside the building as flames raged inside.
Israel has repeatedly targeted both Hezbollah and Hamas officials in Lebanon since the Gaza war erupted almost a year ago.
A strike in January, which a US defence official said was carried out by Israel, killed Hamas deputy leader Saleh al-Aruri and six other militants in Hezbollah's south Beirut stronghold.
In August, an Israeli strike on a vehicle in the south Lebanon city of Sidon killed Hamas commander Samer al-Hajj.
Lebanon's official Palestinian refugee camps were created for Palestinians who were driven out or fled during the 1948 war at the time of Israel's creation.
By longstanding convention, the Lebanese army stays out of the camps and leaves the Palestinian factions to handle security.
The latest developments come as Israel also launched a fresh wave of air strikes against Houthi targets in Yemen.
The Houthis launched a ballistic missile attack toward Israel's Ben Gurion airport on Saturday when Netanyahu was arriving, prompting Israel to retaliate with its own attacks.
The IDF said it targeted power plants and sea port facilities in the city of Hodeida, with pictures circulating on social media showing huge explosions.
Yemen's Houthi-run Health Ministry said the strikes killed four people and wounded 40 others, but the rebels claimed they took precautionary measures ahead of the strikes, emptying oil stored in the ports, according to Nasruddin Ammer, deputy director of the Houthi media office.
He said in a post on X that the strikes won't stop the rebels' attacks on shipping routes and on Israel.
The Israel-Hamas war has escalated in recent days after the IDF said it had wiped out Hezbollah's top brass in the airstrike on southern Beirut that killed the group's leader, Hassan Nasrallah.
Israeli troops and tanks were last night seen gathering in the north, on their border with southern Lebanon, in apparent preparation for a ground invasion.
The last time Israel launched a ground offensive of Lebanon was in 2006, when 34 days of intense cross-border fighting with Hezbollah ended in a stalemate.
Israel claimed that more than 20 senior Hezbollah members including Ali Karaki – who was in charge of the southern front – were assassinated in the attack on Friday alongside Nasrallah.
Reuters reported Nasrallah's body was found yesterday, and videos circulating on social media purport to show his body being retrieved.
Hezbollah – the Iran-backed terror group in Lebanon – confirmed that Nasrallah, who led it for 32 years, was killed in Friday's strike. Hashem Safieddine is expected to take over as the leader.
Several foreign embassies have now begun to evacuate non-essential staff as the country braces for the possibility of an all-out war.
Continued airstrikes in Lebanon killed at least 100 people on Sunday, according to the Lebanese health ministry.
Workers at the marina told the Mail that staff from the Saudi Arabia embassy had departed from Lebanon by boat on Saturday evening. It was unclear whether the ambassador was among the group.
Last night Israel's defence minister, Yoav Gallant, said: 'Our message is clear – for us, no place is too far.'
Yesterday dozens of Israeli warplanes bombarded several Houthi targets in Yemen, according to Israel's military spokesman.
They destroyed power plants and the nearby Ras Isa port which the IDF claims is used by the terror group to transfer 'Iranian weapons to the region'.
The Al-Mayadeen network reported more than 10 air strikes were carried out on oil tankers in the area as revenge for missile attacks which had been fired into Israel by the Houthi Rebels.
Yemen's Houthis have repeatedly fired missiles and drones at Israel since October 7 in what they say are solidarity attacks for Palestine.
They have also hijacked commercial ships in the Red sea including British vessels.
Israeli forces also said they struck Hezbollah targets across Lebanon.
A civil defence worker who survived a 'precise strike' in Dahiyeh, southern Beirut, said he received a last-minute warning shortly before a missile hit a neighbouring building.
Speaking to our reporter, he said: 'I barely made it. I got a message to evacuate and four minutes later there was a strike'.
Yesterday Pope Francis said that the airstrikes in Lebanon go 'beyond morality'. It comes as British families fled to Beirut airport, with the Government last night once again urging British nationals to leave Lebanon.
Iran has vowed revenge for the death of an Iranian general killed alongside Nasrallah on Friday. Abbas Araghchi, Iranian foreign minister, said the killing of Brigadier General Abbas Nilforoushan 'will not go unanswered'.
A 'barrage of rockets' was launched at northern Israel yesterday afternoon causing red alert sirens to ring out in the Tiberias region.
Since October last year Hezbollah has been firing thousands of missiles at Israeli towns and villages which has led to the semi-permanent displacement of more than 60,000 people.
Tragically 12 children were killed in July by a Hezbollah rocket fired from Lebanon which exploded on a football field in Israel.
Up to 1million Lebanese people have now also been displaced from their homes as a result of the fighting, according to Najid Mikati, the Lebanese prime minister.
He said: 'It is the largest displacement movement that may have happened.'
Mr Netanyahu has vowed to return the 60,000 displaced Israeli citizens to their homes along the Lebanese border.
This week, Herzi Halevi, Israel's chief of the general staff, told troops that the fierce aerial bombardment was to 'prepare the ground for your possible entry'.
And on Wednesday Yoav Gallant oversaw a rehearsal of an incursion, telling soldiers: 'The moment may come when we give an order.'
The last time Israel launched a ground invasion of Lebanon was in 2006, when Hezbollah fired rockets at Israeli border towns.
However, the Shia militia has faced almost two weeks of intense bombing that has obliterated Lebanese towns along the border.
'We let them build up again on our border after 2006 and that was a mistake', 39-year-old Yuval, a British citizen and reservist infantryman, whose parents moved to Israel in the 1970s, told The Times.
Yuval, who has spent four months fighting with the IDF in Gaza, added: 'Now there's not a chance in hell we'll let them sit on our border. I understand the world doesn't like conflict. But whether it's with airstrikes or a ground invasion, we need to move them.'
He added: 'The soldiers are ready, the tanks are ready. We know they are waiting for us … I'm tired, but we're here because it's important.'
Energised by the death of Hezbollah's leader, 28-year-old reservist engineer Yehuda told the newspaper: 'We must do what we must do.'
As Israel launch attacks on Lebanon and Yemen, the Houthi-run health ministry said at least four people were killed and 29 wounded in airstrikes on Yemen's port of Hodeidah, which Israel said were a response to Houthi missile attacks.
In Lebanon, authorities said at least 105 people had been killed by Israeli air strikes on Sunday.
On Monday, an Israeli air airstrike hit an upper floor of an apartment building in the Kola district of Beirut, with firefighters seen tackling a blaze.
Lebanon's Health Ministry has said more than 1,000 Lebanese have been killed and 6,000 wounded in the past two weeks, without saying how many were civilians. The government said a million people - a fifth of the population - have fled their homes.
Israeli drones hovered over Beirut for much of Sunday, with the loud blasts of new airstrikes echoing around the Lebanese capital.
Displaced families spent the night on benches at Zaitunay Bay, a string of restaurants and cafes on Beirut's waterfront.
Many of Israel's attacks have been carried out in the south of Lebanon, where the Iran-backed Hezbollah has most of its operations, or Beirut's southern suburbs.
The United States has urged a diplomatic resolution to the conflict in Lebanon but has also authorised its military to reinforce in the region.
President Joe Biden, asked if an all-out war in the Middle East could be avoided, said 'It has to be.' He said he will be talking to Israeli Prime Minister Benjamin Netanyahu.
Meanwhile John Kirby, the White House national security spokesman, warned Netanyahu that he risked a wider regional war by sending his soldiers into Lebanon.
'An all-out war with Hezbollah, certainly with Iran, is not the way to do that. If you want to get those folks back home safely and sustainably, we believe that a diplomatic path is the right course,' he told CNN.
Following the assassination of Nasrallah, Safieddine is expected to take over as the leader of Hezbollah.
Safieddine, his maternal cousin, is also a cleric who wears the black turban denoting descent from Islam's Prophet Mohammed, and has long been tipped as his successor.
It's believed he was born in southern Lebanon and is in his late 50s or early 60s. As young men they studied theology together at Shia institutions in Iraq and Iran.
Safieddine joined Hezbollah soon after it was set up during the Lebanese civil war – after Israel besieged the capital Beirut in 1982.
He heads Hezbollah's political affairs and is a member of the Jihad Council, which manages the group's military operations. The US and Saudi Arabia class Safieddine as a terrorist.
He made headlines in the wake of Hamas' attack on Israel on October 7, 2023, when he confirmed Hezbollah's support for the group. 'Our history and guns and our rockets are with you,' Safieddine said.
Fears of a ground invasion came as Syrians and Iranians celebrated following Nasrallah's death in Lebanon's capital Beirut on Friday.
There were jubilant scenes in the northern Syrian city of Idlib, where people took to the streets honking horns, handing out sweets and thanking Israelis.
Anti-Iranian regime demonstrators also gathered outside the Israeli embassy in Kensington, west London, to welcome Nasrallah's assassination.
In contrast to the scenes of joy outside the Israeli embassy in London, Iran's embassy to the UK in the capital has lowered its flag to half-mast following Nasrallah's death.
The move came as Iran began five days of official national mourning, announced by the country's Supreme Leader Ayatollah Khamenei.
Kaouk had been thought to be among the main contenders to replace Nasrallah, who had led Hezbollah for 32 years.
The Lebanese group's role supporting both the Iranian and Syrian ruling regimes helps explain why many opponents of both have welcomed Nasrallah's demise.
Iran helped establish Hezbollah in the 1980s and has provided the Lebanese militant group with sophisticated weaponry and training.
Hezbollah has also aided Syria's President Bashir al-Assad in his crackdown on rebels in that country's civil war which has been raging since 2011.
Syria's government condemned Nasrallah's killing in Friday's strikes, in contrast to the jubilant response in rebel-held Idlib where people waved Syrian flags, cheered and handed out treats.
One person wrote on X, formerly Twitter: 'I'm in Idlib right now and the Syrians are out on the streets celebrating rumours of the death of Nasrallah, the leader of Hezbollah, aka Hezboshaytan!
'Just a few days ago Hezboshaytan bombed a village here, today we buried a one-year-old baby and his mother that were killed.'
Another video posted on social media showed women in Iran, covering their faces, welcoming the news of Nasrallah's death.
A speaker said: 'The children of Iran send a congratulatory message to everyone for the death of Hassan Nasrallah and congratulate the Iranian nation.'
