US Department of Defence has said that the new air-defene system installed by Pakistan was of no consequence for America as it posed no danger to their forces deployed in Afghanistan, Geo News reported.

A briefing by Pentagon also stressed that to avoid another Mohmand attack better coordination was the way to go not an air-defence system, adding such tactical decisions were Pakistan’s internal affairs.

The briefing added that warmer Pakistan-US ties were in the broader interest of both strategic partners in war on terror.

Pentagon officials also adamantly maintained that Nato’s attack in Mohmand was involuntary.
