Iraqi supporters of an Iranian-backed militia on Tuesday stormed the US embassy compound in Baghdad and set it partly aflame during a rowdy demonstration that has raised tensions between Tehran and Washington. 

The protesters broke down the US embassy gate door and managed to make their way into the security kiosk at the entrance of the heavily guarded compound, as gunshots and sirens rang out in the Iraqi capital, according to news organisations and video footage. 

Security forces fired tear gas and stun guns in an attempt to disperse the hundreds of protesters, injuring at least two bloodied militiamen. The guard towers protecting the massive compound also appeared to be on fire. 

Donald Trump blamed Iran for both the attack on the military facility and the embassy attack. 

“Iran killed an American contractor, wounding many. We strongly responded, and always will”, - he wrote on Twitter. - “Now Iran is orchestrating an attack on the U.S. Embassy in Iraq. They will be held fully responsible. In addition, we expect Iraq to use its forces to protect the Embassy, and so notified!”.
