A bomb tore apart a bus thought to be carrying Lebanese Shiite Muslim pilgrims in Damascus on Sunday, killing at least six people and wounding 19 in a rare attack at the center of the Syrian capital, a Reuters witness and local media said.
A social media account linked to al-Qaida's Nusra Front said the hardline Sunni group was behind what it described as a suicide attack on the bus near a marketplace.
The vehicle had Lebanese number plates and Syrian security services had cordoned off the area close to Hamidiyeh market, the Reuters witness said. Rescue workers sifted through the rubble and cleared away pools of blood from the ground.
