Five explosions shook Istanbul on Thursday, including blasts in front of the HSBC bank in an affluent district and another across the British consulate, television stations reported. Body parts were scattered in front of the HSBC bank in Levent district, NTV television reported based on witness accounts. Another bomb explosion ripped of the wall surrounding the garden of the British consulate in downtown Beyoglu district. Ten people were reported killed in that explosion, private CNN-Turk television said. Two more explosions followed, including one on the Asian side of this city, televisions said. The blasts followed Saturday's suicide attacks on two synagogues by two Turkish militants that killed 23 people. Al-Qaida claimed responsibility for the synagogue attacks but authorities were trying to authenticate that claim.
