KABUL, Afghanistan (AP) — Afghan officials say 48 people have been killed in a suicide bombing targeting Shiite worshippers in Kabul. The attacker blew himself up Tuesday in the midst of a crowd of men, women and children gathered outside the Abul Fazl shrine to commemorate the seventh century death of the Prophet Muhammad's grandson Imam Hussein. Mohammed Zahir, chief of the Kabul Criminal Investigation Department, gave the death toll and said more than 100 people were wounded. Officials say four other people were killed when a bomb strapped to a bicycle exploded as a convoy of Afghan Shiites drove by in the northern city of Mazar-i-Sharif.
