In Afghanistan, at least 23 people were killed and more than 100 others were wounded Sunday after a suicide bomber struck near Kabul’s main airport. The attack ripped through a crowd of supporters of Afghan Vice President Rashid Dostum, an ethnic Uzbek politician who had just returned to the Afghan capital after more than a year of self-imposed exile. Dostum was unharmed in the explosion. Dostum left Afghanistan last year, after the country’s attorney general ordered the arrest of his bodyguards for allegedly torturing and sexually assaulting a rival politician. Dostum was also involved in a massacre in 2001 that killed up to 2,000 Taliban prisoners of war. Elsewhere in Afghanistan Sunday, gunmen stormed a mosque in eastern Nangarhar province, opening fire and killing four worshipers during evening prayers.
