 A blast on an army bus in Damascus has killed 14 people. State media reported that it is the deadliest bomb in the Syrian capital in years, quickly followed by army shelling in rebel-held Idlib. Rescue workers said 12 people were killed. A roadside bomb attack in Syria's capital, Damascus killed over a dozen military personnel on Wednesday. State media reported that a bus carrying the soldiers was crossing a bridge in central Damascus during early morning rush hour when two explosive devices went off. Images of the charred cabin of the bus were shared on Syrian state TV's Telegram account, and rescue workers removing body parts from the scene. A third device was diffused by an army engineering unit. No group has yet claimed the attack, but officials have called it a terrorist blast. There have been several attacks this year on army vehicles in eastern Syria by suspected Islamic state militants who still operate in the sprawling desert area. But blasts in Damascus are rare. That's because forces loyal to President Bashar al-Assad took control of rebel enclaves around the city.
