Pakistani police say they have arrested six suspected Islamist militants from an al-Qaida-linked group during a raid on a home in the southern port city of Karachi. Police say they also confiscated heavy weapons and explosives.
The six men are believed to be from an outlawed Sunni Muslim group known as Lashkar-e-Jhangvi. Lashkar-e-Jhangvi is regarded as Pakistan's fiercest Sunni militant group. It is accused of killing minority Shi'ite Muslims since its emergence in the early 1990s. Pakistan's President Pervez Musharraf banned the group in August 2001.
Last month, a suicide blast in Karachi killed more than 50 people including top leaders of the moderate Sunni Tehreek group. It was not clear if the arrests were linked to last month's attack.
