A bomb blast inside a Shi’ite mosque during evening prayers killed 14 people on Monday in Karachi. Doctors said they had counted 14 dead and hospitals had admitted more than 55 wounded, while wailing men and women searched in the darkness for relatives lost in the wreckage under the cracked dome of the city centre mosque.An angry crowd set fire to nearby vehicles and prevented police from approaching the scene, letting through only ambulances. Karachi had feared fresh inter-Muslim sectarian violence after the killing on Sunday of Mufti Nizamuddin Shamzai, a radical Sunni preacher, and thousands of police were on duty at the city’s mosques in anticipation of a backlash.The government’s chief spokesman told Geo TV that President Pervez Musharraf planned to take tough measures to restore order in the city. ‘‘I will take serious action, this is the second incident within 24 hours, following Mufti Shamzai’s killing,’’ Information Minister Sheikh Rashid Ahmed quoted Musharraf as saying. — Reuters
