In the Afghan capital, an explosion in a mosque wounded at least six people attending prayer. Someone threw a hand grenade at the mosque in central Kabul on Wednesday. Officials said one suspect has been arrested. It's the second blast to hit the capital in a week. An explosive device went off near a money exchange market on Sunday, which killed one person and wounded dozens. Taliban authorities said they have secured the country since taking over in August and most fighting has since ended. But international analysts say the risk of a resurgence in militancy remains as the Islamic State terrorist group has claimed several major attacks.
