WATCH: No missiles intercepted in attack on US bases, heavy casualties reported

There have been initial reports of casualties.

The reprisal was staged in the early hours of Wednesday, hitting Ain al-Assad Airbase in the western Iraqi province of Province and another outpost in Erbil, the capital of Iraq’s semi-autonomous Kurdistan region.

The attacks were launched at 1:20 a.m. local time, the moment the US military launched drone strikes on Friday that led to the martyrdom of General Soleimani, the commander of the Islamic Revolution Guards Corps (IRGC)’s Quds Force, and the second-in-command of Iraq’s Popular Mobilization Units (PMU) anti-terror group, Abu Mahdi al-Muhandis, among others, in the Iraqi capital, Baghdad.

General Soleimani was cooperating with the PMU and the Iraqi government against the most deadly terrorist outfits to ever afflict the region, including the Daesh Takfiri group.

The Islamic Republic had denounced the assassinations as “an act of state terrorism.”

Tehran had also said it reserves the right to respond in kind, with Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei famously warning about “harsh revenge” in a speech that followed the assassinations.
