Pakistani police have arrested two suspected Islamic militants in connection with last week's deadly suicide attack on a Shi'ite mosque in Karachi that killed five people, including two attackers.

Karachi's senior police official Fayyaz Khan says authorities captured the pair during a pre-dawn raid on a hide-out in the city's eastern district. He says police also recovered explosives, two grenades and a pistol during the raid.

The men belong to an outlawed militant group, Lashkar-e-Jhangvi, which has links with Osama bin Laden's al-Qaida terror network.

The May 30 mosque attack sparked riots in Karachi, where an angry mob torched a crowded U.S. fast-food outlet, killing six employees. The rioters also attacked a hospital and two gas stations, and bombed buses and cars.
