Mourners Gather in Karachi After Deadly Bombings VOA News 06 February 2010 Pakistani Shiite Muslims carry coffins of the victims of Friday's bombing during a funeral prayer in Karachi, Pakistan, 06 Feb 2010 Photo: AP Pakistani Shi'ite Muslims carry coffins of the victims of Friday's bombing during a funeral prayer in Karachi, Pakistan, 06 Feb 2010 Thousands of mourners gathered in the southern Pakistani city of Karachi Saturday amid high security to attend funerals for some of the 31 people killed in two bomb attacks the day before. The death toll rose as several people died overnight. Some of the bombing victims were marking the end of 40 days of mourning for the Prophet Muhammad's grandson. The Shi'ite ritual takes place each year. Karachi has been the scene of sporadic violence between Sunni and Shi'ite Muslims in the past. The city was tense Saturday. Many businesses were closed. Officials say a suicide bomber on a motorcycle rammed a bus carrying Shi'ite Muslim pilgrims Friday. Later in the day, a bomb exploded outside the entrance to the emergency ward of a hospital treating victims of the first blast. Police say they defused a third bomb at the hospital. Karachi also had an upsurge in ethnic violence in the past week. At least 26 people were killed in clashes between activists from rival political parties - the Muttahid Qaumi Movement and the Awami National Party, which traditionally gather support from different ethnic groups. Some information for this report was provided by AFP and AP. .
