CAIRO (Reuters) - Islamic State claimed responsibility for a deadly attack on Saturday in the western Afghan city of Herat, it said in a post on Telegram on Sunday.

       At least six people were killed when a blast ripped through a minivan in the city, officials said. Since the Taliban took over in August, a series of blasts and attacks, some claimed by Islamic State, have taken place across Afghanistan.
