The so-called Islamic State has claimed responsibility for two suicide bomb attacks in Beirut that left at least 43 people dead and more than 240 wounded.
The bombings took place in a crowded residential district in the Lebanese capital's southern suburbs - a stronghold of the Shi'ite Muslim group Hezbollah.
The attacks come at a time that Hezbollah is stepping up involvement in the Syrian civil war, sending hundreds of fighters to support President Bashar al-Assad's forces in the conflict with mostly Sunni insurgents, including IS.
The action has prompted Sunni Islamist threats against the Iran-backed group.
Thursday's blasts struck a community centre and a nearby bakery in the commercial and residential area of Borj al-Barajneh, according to security sources.
In a statement posted online by its supporters, Islamic State said its members blew up a bike loaded with explosives - with a second suicide bomber waiting for crowds to gather before detonating his own device.
