At least 22 people were killed in a double suicide bomb attack at an army checkpoint in the central Syrian city of Homs on Tuesday, state media said.

In a breaking news alert, state television said 100 people had also been injured in the blasts in the Al-Zahraa neighborhood of the city, which has been targeted in bomb attacks multiple times before.

The provincial governor of Homs, Talal Barazi, told AFP the two bombers appeared to have pulled up at the army checkpoint in a car together, with one exiting the vehicle before the other detonated his explosives while still inside.

In the chaos of the first blast's aftermath, and as a crowd gathered, the second bomber detonated his explosives, Barazi said.

The Al-Zahraa district of Homs has been targeted in multiple bomb attacks in the past, including in late December, when 19 people were killed in several simultaneous blasts.
