Two suicide bombers blew themselves up within minutes of each other Monday at an anti-drug police station in southwest Afghanistan, killing one officer and wounding two more, an official said. The first suicide attacker, wearing civilian clothes, approached the station in the southern city of Zarang at about 11 a.m., said Gov. Ghulam Dastagir Azad. When police shouted for the man to stop, he blew himself up, causing no casualties, the governor said. Minutes later, a second attacker wearing a police uniform approached the building and blew himself up, Azad said. That blast killed one officer and wounded two. Azad said the double suicide attack mirrored tactics used by eight militants in an assault against three government buildings in Kabul earlier this month that killed 20 people.
