Timeline: How a day of terror in Sri Lanka unfolded

A series of bombs ripped through churches and hotels in Sri Lanka on Easter Sunday, killing at least 290 people and injuring hundreds. Several of those bombs went off inside churches, during Easter services in three cities.

Sri Lanka’s minority Christian community, which accounts for less than 10% of the country’s total population of 21.4 million, appeared to be the main target of the coordinated attacks.

Though it wasn’t immediately clear who was behind the eight explosions that paralyzed the country, Manisha Gunasekera, high commissioner of Sri Lanka to the UK, said the blasts are “certainly acts of terror.” Ten days before the attack, an intelligence memo warning of a possible attack had been circulated, raising questions about whether more could have been done to prevent the attack. An island-wide curfew was implemented until the following morning.

Here’s what we know about each location attacked on Sunday.
