The al Qaeda-linked Abdullah Azzam Brigades had urged Lebanese Sunni Muslims to attack the Iranian-backed Shi'ite militant group Hezbollah a day before Wednesday's suicide bombing in central Beirut.
No claims of responsibility have been made for the attack but the Abdullah Azzam Brigades says it has carried out recent bombings in Lebanon, including an attack on the Iranian embassy in November which killed 23 people, mostly civilians.
"The soldiers of the Party of Iran (Hezbollah) and its leaders are beneath you, so gain the approval of Allah by killing and assassinating them!" Sirajuddin Zurayqat, a cleric for the group, said in the audio message. (Reuters)
