On a day of national mourning in Lebanon, hundreds of people turned out for the funeral of two victims of Friday’s mosque bombings in Tripoli.
At least 45 people were killed in the attacks, which targeted Sunni Muslims at Friday prayers.
The Tripoli attacks come one week after an explosion in Beirut killed 20 Shi’ite Muslims.
The sectarian violence appears to be increasing and there are fears it may be linked to the fighting in Syria.
The Lebanese government is accusing “terrorists” of provoking “sectarian strife by targeting different regions”.
Lebanese caretaker Prime Minister Najib Mikati said: “We are pretty sure that the incidents in Beirut’s southern suburb and Tripoli yesterday were by the same people. We are not calling for reconciliation really, nor are we accusing each other of planting bombs. What we need to do is unite in order to fill any void that might come about. “
Lebanon’s Interior Minister Marwan Charbel says 800 people were injured in the Tripoli blasts.
Bombings targeting civilians in Lebanon are not common. However, Tripoli, 80 kilometres north of Beirut, does have a reputation for being volatile.
Al Qaeda’s north African branch, al Qaeda in the Islamic Maghreb (AQIM), has accused Shi’ite Lebanese group Hezbollah of carrying out the attacks.
