Explosion rocks Christian area north of Beirut

A bomb went off in a Christian area north of Beirut on Thursday, in the latest string of explosions that have shaken Lebanon since fighting erupted between army troops and Islamic militants in a northern refugee camp three weeks ago. Security officials said the blast occurred in an industrial area in the town of Zouk Mousbeh, about 20 kilometers (12 miles) from Beirut. There was no immediate word on casualties.
