US and Afghan forces have stepped up attacks against the Haqqani Network in eastern Afghanistan over the past several days. More than a dozen fighters have been killed and 21 more were captured, including a commander, during airstrikes and raids since June 27.
The US military reported that "more than a dozen militants" were killed during a series of airstrikes against "a pair of command bunkers" in a mountainous region in Khost province near the border of Pakistan.

Forward Operating Base Salerno, Afghanistan -- In the enveloping darkness of a starless summer night, the sizzle-thump of incoming Taliban rockets is swiftly answered by the percussive boom of outgoing U.S. artillery. But the American troops manning this base in eastern Afghanistan know that their elusive nighttime foe can slip away to sanctuary in Pakistan, just 20 miles away.
The militants firing rockets at this installation, informally known as Camp Salerno, in all likelihood traveled here from Pakistan's tribal areas, home turf of several major Taliban commanders and their militias. The flow of fighters and arms into Afghanistan from Pakistan -- and the tribal belt's use as a fighter haven -- has long been a key concern of U.S. and other Western officials.
