Explosion rocks Christian area of Lebanon

(CNN) -- Two people were wounded late Monday when an explosion rocked a commercial center in a Christian suburb north of Beirut, according to a Lebanese security source and local media reports.

Just last month a powerful explosion rocked a Christian area of Beirut. Hours after U.S. Secretary of State Condoleezza Rice paid a surprise visit, the second major blast in two weeks shook the Lebanese capital on July 22. No deaths were reported.

On July 12 Lebanon's outgoing deputy Prime Minister Elias Murr was among 12 people wounded by a blast that tore through a Christian neighborhood in northern Beirut. At least two people were killed.
