Soleimani's coffin arrives at Tehran airport

The body of General Qassem Soleimani arrived in Tehran on Sunday, after a day of mass mourning for the top Iranian general who was killed in a U.S. drone strike in Baghdad on Friday. At Tehran's Mehrabad Airport, the caskets of Soleimani and others killed in the airstrike were carried through a crowd of supporters. 

Earlier, hundreds of thousands of people flooded the streets in the cities of Ahvaz and Mashhad to walk alongside the casket of Soleimani, who was the architect of Iran's proxy wars across the Mideast and was blamed for the deaths of hundreds of Americans in suicide bombings and other attacks.

Meanwhile, the blowback over the killing mounted as Iran announced it will no longer abide by the limits contained in the 2015 nuclear deal and Iraq's Parliament called for the expulsion of all American troops from Iraqi soil.

The twin developments could bring Iran closer to building an atomic bomb and enable the Islamic State group to stage a comeback in Iraq, making the Middle East a far more dangerous and unstable place.
