At least 29 people were killed in Kabul, Afghanistan, Wednesday morning and 52 injured when a suicide bomber detonated an explosive device on the road to a Shiite shrine. Wednesday is the Persian new year, Nowruz, which Afghanistan's minority Shiites celebrate by visiting shrines. The Islamic State, a Sunni group, claimed responsibility for the attack through its Aamaq news agency. Interior Ministry spokesman Najib Danesh said the bomber, traveling on foot, was trying to get to the shrine, which has been attacked before. "We had our security in place in and around the shrine," he said. "All the casualties were young men who were either passing by on the road or gathering to enjoy Nowruz."
