Two rockets fired at Hezbollah-controlled southern Beirut bring Syria's escalating civil war deeper into the heart of Lebanon and closer to unrestrained regional conflict.
The two-year-old conflict in Syria has already tumbled into Lebanon's Bekaa Valley, exploded into deadly street fighting in its northern city of Tripoli and driven half a million refugees across the same porous border to escape the bloodshed.
But Sunday's rocket attack, which wounded five people in a Shi'ite neighborhood of Beirut, marked the first apparent targeting of Hezbollah's stronghold in the south of the capital and raised memories of years of civil war in the city.
