Lebanese authorities say 12 people were injured in a blast on a crowded street in predominantly Christian East Beirut Friday.

Security officials say the bomb was placed near a car and destroyed several vehicles parked on Rue Monot Street filled with restaurants and nightclubs

In the last few months, Lebanon has seen a wave of car bomb explosions, mainly assassinations of anti-Syrian politicians and journalists.

Friday's blast followed by several hours the visit to Beirut of U.S. Secretary of State Condoleezza Rice. She was in the Lebanese capital on a brief, unannounced visit to meet with top government officials.
