Update, 3:33 pm: Extremist group Islamic State in Syria and Iraq (ISIS) reportedly claimed responsibility for the twin blasts in the city of Homs in Syria.
While the state media reported the death of at least 22 people, ISIS claimed it killed at least 30 people, according to Reuters.
At least 22 people were killed and over 100 injured on Tuesday when a suicide attacker detonated an explosive belt and a car bomb exploded in western Syria's pro-government city of Homs.
The car bomb went off first at a security checkpoint, followed by the suicide bombing, Syrian state TV quoted Homs Governor Talal Barazi as saying, according to Reuters.
The al-Zahra neighbourhood, with residents from the Alwaite minority, which dominates the ruling Syrian government, was target of the twin blasts, Xinhua cited SANA news agency as saying.
