Pakistan Taliban claims responsibility for attacks killing 25 as world leaders gather The religious festival of Muharram, a 10-day period when processions mourn the death of the Prophet Mohammed's grandson, ends on Sunday and is a particular target of Sunni extremists. The Pakistan Taliban claimed responsibility for three attacks carried out on the eve of the D8 summit and said more would follow. "People belonging to Shia community are infidel and blasphemous and we will not spare them," said a spokesman. You will see further attacks in coming days. Shiﾒites have reported receiving threatening text messages. "Kill, Kill, Shi'ites," say the text warnings to members of the minority sect. Witnesses to the attack in Rawalpindi said a suicide bomber threw a grenade into a procession on its way to a mosque, before detonating an explosive vest. Deeba Shehnaz, a police rescue spokeswoman, said: "A total of 23 people have expired and 62 injured, eight of them are children." Earlier, a blast outside a Shia mosque in the southern city of Karachi killed at least two people, and gunmen in north-west Pakistan killed four police officers in an ambush.
