For over two decades Soleimani had been at the forefront of projecting the Islamic Republic's military influence across the Middle East.
Former Iraqi PM condemned the Soleimani's killing and said that it would light the "fuse of war".

Abdul Mahdi, whose government has the backing of Iran, said in a statement the US airstrike was "a dangerous escalation that will light the fuse of a destructive war in Iraq, the region, and the world."
