At least 37 people were killed and 180 are injured after twin suicide blasts on Thursday in the Lebanese capital, Beirut.
The almost simultaneous explosions hit a southern suburb that is a stronghold of the Shi’te Muslim militant group Hezbollah.
Medics rushed to treat the wounded in the busy commercial and residential district of Borj al-Barajneh,
where two suicide bombers blew themselves up outside a shopping centre and a Shi’ite community centre.
A third would-be bomber is said to have been killed by one of the explosions.
The blasts are the first attacks for more than a year in a stronghold of Hezbollah.
The conflict in neighbouring Syria has spilled over into Lebanon, which is still rebuilding after its own 15-year civil war.
Hezbollah fighters are battling in Syria on the side of President Bashar al-Assad against Sunni insurgents including the so-called Islamic State.
