Iran has launched 'more than a dozen ballistic missiles' at two targets hosting US military and coalition forces in Iraq.
Reports suggest two types of ballistic missiles were used to hit US Military bases in Ain al-Asad in western Iraq and also around Erbil in Iraqi Kurdistan.
The majority of those used are believed to be the Fateh-110, which can travel 180 miles or 300km and have a payload of around 500lb.
But reports also suggest the Qiam-1 was also used, a short range ballistic missile produced by Iran which can travel 500 miles and carry 750lb warheads.
Iran has fired more than a dozen ballistic missiles at two Iraqi bases housing American troops in a revenge attack for the U.S. drone strike that killed a top Iranian general
The Pentagon says the missiles were 'clearly launched from Iran' to target U.S. military and coalition forces in Iraq
The former an Iranian-designed, short-range, surface-to-surface ballistic missile can be launched from any location while the latter was specifically built to target US bases in the Middle East, which have 'encircled Iran', according to Iranian sources.
When it was launched the Fateh-110 was described by Iranian defence minister Brigadier General Amir Hatami as '100-percent domestically made - agile, stealth, tactical (and) precision-guided'.
Both missiles are reported to have been fired from Tabriz and Kermanshah provinces in Iran.
US Defense Department spokesman Jonathan Hoffman said: 'It is clear that these missiles were launched from Iran.'
He added that the attacks 'targeted at least two Iraqi military bases' at Ain Assad and Erbil.
Mr Hoffman said the US is 'working on initial battle damage assessments.'
The Ayn al Asad airbase in western Iraq that was visited by Donald Trump in December 2018 and the Erbil base in Iraqi Kurdistan were both struck by the missiles on Tuesday at about 5.30pm (EST)
