Beirut blast kills at least two in Hezbollah stronghold
The blast caused damage across a wide area At least two people have died after a strong blast hit a southern suburb of the Lebanese capital Beirut, local media and residents say.
The suburb is a stronghold of the Shia militant group Hezbollah.
Hezbollah's own TV station said the blast occurred in a densely populated area of Haret Hreik district.
The city has recently been hit by a wave of attacks linked to heightened Sunni-Shia tensions over the Syrian war.
Former minister Mohamad Chattah, a Sunni and a critic of Hezbollah, was killed by a car bomb in central Beirut last Friday.
Hezbollah's al-Manar TV showed large crowds gathered around twisted and burnt-out vehicles in front of a building that had been badly damaged in Thursday's blast.
Ambulances are at the scene.
