KABUL, Afghanistan (AP) — Seven insurgents wearing police uniforms and bombladen vests attacked a government compound in a usually secure province in eastern Afghanistan today, killing one police officer, officials said.

The Taliban, which claimed responsibility for the attack, has ramped up its assaults on government forces and officials since launching its spring fighting campaign earlier this month. While the attacks have grown more frequent in many parts of Afghanistan, today’s violence was of note because it took place in the eastern Panjshir province, a normally peaceful area in a valley that was the heart of the anti-Taliban resistance until the U.S. invasion in late 2001.

Governor Kramuddin Karim said the attackers targeted the government complex in the provincial capital of Bazarak, and that all seven militants were killed.

Taliban spokesman Qari Yousef Ahmadi claimed responsibility for the attack in an email to journalists.
