Iraqi Prime Minister Mustafa al-Kadhimi escaped unharmed from an assassination attempt by three armed drones in Baghdad on Sunday, officials said. The assassination attempt came weeks after a general election was disputed by Iran-backed militia groups.

The attempt dramatically raises tension in the country that has already seen threats of violence.

Al-Kadhimi took to social media moments after the attack and called for “calm and restraint from everyone.”

“Thank God, I am fine and among my people,” he posted on Twitter.
