Bomb explodes at Hezbollah checkpoint in eastern Lebanon

BEIRUT (Reuters) - A car bomb exploded at a checkpoint controlled by Shi'ite Muslim group Hezbollah in eastern Lebanon on Saturday, security sources and the state news agency NNA said, without giving information on casualties.

The explosion took place outside the village of Khraibeh in Lebanon's Bekaa Valley, a region that has experienced increased violence and spillover from Syria's civil war next door.

It was not clear who was behind Saturday's attack.
