Four people were killed yesterday in a car bomb blast targeting a military bus on the outskirts of the northern Lebanese port city of Tripoli.
The attack risks further undermining stability in the troubled country and efforts to reconcile rival political factions.
A military official said three of the casualties were soldiers, as were 24 of the 30 people wounded.
The bomb, placed under a parked car at the southern entrance to the city, was packed with nuts and bolts and police suspect the device was detonated by remote control.
It blew up as the bus was heading towards the capital Beirut during morning rush-hour, a military spokesman said.
Police and the army cordoned off the area as forensic experts began gathering evidence while residents raced to the scene or to nearby hospitals to look for their loved ones.
The force of the blast shattered windows and damaged cars nearby. The vehicle under which the bomb was placed was left a burned-out pile of twisted metal. AFP
