...Afghanistan officials claimed Sunday that Afghan and NATO forces were retaliating for gunfire from two Pakistani army bases when they called in airstrikes that killed 24 Pakistani soldiers, adding a layer of complexity to episode that has further strained Pakistan’s ties with the United States.

The account challenged Pakistan’s claim that the strikes were unprovoked... http://www.suntimes.com/news/world/9102087...

...But a report in Monday's Wall Street Journal -- denied by Islamabad -- said the Nato jets and helicopters responded to firing from a Pakistani post on the ill-defined Afghan border.

The article, which followed a similar report by Britain's Guardian newspaper, cited three Afghan officials and one Western official as saying the air raid was called in to shield allied forces targeting Taliban fighters.

Nato and Afghan forces "were fired on from a Pakistani army base", the unnamed Western official told the Wall Street Journal. "It was a defensive action."

An Afghan official in Kabul was quoted as saying: "There was firing coming from the position against Afghan army soldiers who requested support and this is what happened."... http://www.hindustantimes.com/world-news/P...

This is still only part of the story...

There is an excellent BBC Documentary out about how Pakistan has been playing a double game:

..."The ISI of course... must take responsibility for the fact that some of these camps were still up and running including perhaps the camp that, that was responsible for training the 7/7 attackers."

Yet initially the evidence of Pakistan's double role was largely disregarded.

According to the former British Ambassador to Afghanistan Sherard Cowper Coles: "Somehow because the Pakistani dimension was too difficult, too enormous, we just sort of shut it out and pretended that by pushing the insurgents around Helmand or out of bits of Helmand, that was somehow solving the problem."

The series reveals that by 2009 evidence of a double cross was too strong to be further ignored.

Bruce Riedel, a former CIA officer, who headed a secret review of Pakistan's role for President Obama, describes briefing the President: "I spoke pretty much non-stop for about 45 minutes, and then we spent another hour, hour and a half, talking about it...

"I told the President Pakistan was double-dealing us and that the Pakistanis had been double-dealing the United States and its allies for years and years, and they were probably going to continue to do so." ... http://www.bbc.co.uk/pressoffice/pressrele...
