ISIS suspected of carrying out twin car bomb blasts in Syria which kill at least 46 and wound more than 100 in one of the civil war's deadliest attacks yet 

Two blasts in the central Syrian city of Homs killed at least 46 people in one of the deadliest attacks to hit the city in five years of civil war. 

More than 100 people were wounded in the twin car bomb attacks in the city centre's Zahra district, according to the Britain-based Syrian Observatory for Human Rights. 

Syrian state television quoted Homs provincial governor Talal Barazi as saying at least 25 people had been killed. 

Graphic footage from pro-Assad television channels showed charred corpses buried among rubble, damage to shop fronts and debris littering a wide area. Many cars were on fire, sending out plumes of black smoke. Wounded people walked around dazed.

The Observatory said the attack was the second most deadly of its kind in Homs since 2011, and the deadliest for almost a year and a half.

Once dubbed the capital of the Syrian revolution, Homs city is now almost completely controlled by the Syrian government.
