BEIRUT, Lebanon — An explosion on Sunday ripped apart a bus carrying Lebanese pilgrims to Shiite shrines in Damascus, Syria, killing at least six people and wounding 27, official news channels reported.
The attack stood out for striking a specific vehicle in a tightly secured area just outside the Syrian capital’s Old City, and speculation quickly rose that Hezbollah fighters could have been targeted, or that the attack was a baldly sectarian provocation.
