In Afghanistan, at least 20 people were killed and 50 others wounded Sunday after suicide bombers targeted the offices of a leading vice-presidential candidate in the capital Kabul. The blasts preceded an hours-long gun battle that saw more than 150 civilians forced to evacuate the four-story office building. No group has claimed responsibility for the attack, which targeted Amrullah Saleh, Afghanistan’s former intelligence chief and running mate to President Ashraf Ghani, who’s seeking another term in elections scheduled for September 28.
