KABUL, Afghanistan – A suicide bomber blew himself up on the road to a Shiite shrine in Kabul on Wednesday, where people had gathered to mark the Persian new year. At least 26 people were killed and 18 wounded, Deputy Spokesman for the Ministry of Interior Nasrat Rahimi told CBS News. The Persian new year, known in Afghanistan as Nauruz, is a national holiday. The country’s minority Shiites typically celebrate by visiting shrines. No one immediately claimed responsibility for the attack, and the Taliban denied involvement. Afghanistan is home to a powerful Islamic State of Iraq and Syria (ISIS) affiliate that has repeatedly targeted Shiites, who the extremists view as apostates deserving of death.
