A remote-controlled roadside bomb killed three police officers in eastern Afghanistan on Sunday, an attack the Taliban claimed as the opening round of their spring offensive. According to AP, the bomb exploded in Ghazni province beneath a police convoy that was traveling to the district of Zana Khan to take part in a military operation against insurgents, Mohammad Ali Ahmadi, the province's deputy governor, told The Associated Press. He said the blast destroyed the vehicle carrying Col. Mohammad Hussain, the deputy provincial police chief, killing him and two other officers. Ahmadi said two officers also were wounded in the insurgent operation, adding that it clearly targeted Hussain. Taliban spokesman Zabiullah Mujahid claimed responsibility in an email sent to the media.
