JALALABAD, Afghanistan (AFP) -- A suicide attacker dressed as a woman detonated bombs strapped to his body at a checkpoint on Afghanistan's border with Pakistan Tuesday, killing a policewoman, an official said.

The man, dressed in an all-covering burka that most Afghan woman wear when in public, blew himself up in a room at the Torkham border post used for searching women travelers, a provincial government spokesman said.
“The burka-clad suicide attacker detonated his explosives at the search room for women and killed one border policewoman,” Nangarhar province spokesman Ahmad Zia Abdulzai told AFP.
Three male policemen and six civilians were injured, he said.
The wounded were rushed to hospitals across the border in Pakistan and there was no immediate word on their condition, Abdulzai said.
No one claimed responsibility for the attack but most similar bombings are claimed by insurgents from the Taliban militia that was ousted from power in late 2001 by a U.S.-led invasion of Afghanistan.
The insurgents have intensified their attacks as Afghan and international troops launch operations to clear them out of hotspots ahead of the August 20 presidential and provincial council elections.
There are concerns the violence may derail the elections and Afghanistan's partners are sending in thousands of military reinforcements.
