Tensions have recently escalated in the region, with Iraq caught in the middle of the clashes.
On Friday, Iran's top military commander Qassem Soleimani was killed in the US targeted attack on the Baghdadi International Airport. Iran took its "revenge" by conducting airstrikes on US military bases in Iraq on Wednesday.
