The United States embassy in the Syrian capital Damascus has been targeted by car bombers who also tried to storm the building. At least one car bomb was involved. Some reports say attackers tried to crash a vehicle through the heavily-fortified compound. Other accounts say it was left parked outside. Shouting religious slogans, four men are said to have thrown a grenade into the yard of the complex. But the assault was repelled by security forces. Describing the attack as a “terrorist operation”, Syria’s Interior Minister Bassam Abdel Majid said three of the men were killed and a fourth injured.
