An explosion Wednesday caused several cars to burst into flames in a Christian suburb east of the Lebanese capital. A local television station, LBC, said four people were killed and 20 wounded.
Security officials could not immediately confirm the casualties, but Lebanon has been rocked by a series of mysterious bombings in recent years, many of them targeting anti-Syrian figures.
The explosion occurred in the Sin el-Fil district, but the cause was not immediately known. Television footage showed severe damage in nearby buildings and several cars on fire. The blast sent a cloud of gray smoke over the area.
