“Martyrdom was the reward for his ceaseless efforts in all these years,” Iran’s supreme leader Ayatollah Ali Khamenei tweeted.

“With him gone, God willing, his work and his path will not be stopped, but severe revenge awaits the criminals who bloodied their foul hands with his blood and other martyrs’ in last night’s incident,” he said.

“The US’ act of international terrorism, targeting & assassinating General Soleimani–THE most effective force fighting Daesh (ISIS), Al Nusrah, Al Qaeda et al–is extremely dangerous & a foolish escalation. The US bears responsibility for all consequences of its rogue adventurism,” Iran Foreign Minister Javed Zarif tweeted.

“At the direction of the President, the U.S. military has taken decisive defensive action to protect U.S. personnel abroad by killing Qasem Soleimani, the head of the Iranian Revolutionary Guard Corps-Quds Force, a U.S.-designated Foreign Terrorist Organization,” the White House said in a statement later.
