Karachi : Pakistani protesters, some holding banners reading, “Attack on Pakistani posts is barbaric act”, march to condemn NATO airstrikes on Pakistani troops, in Karachi, Pakistan, Sunday, Nov. 27, 2011. Afghan troops and coalition forces came under fire from the direction of two Pakistan army border posts, prompting them to call in NATO airstrikes that killed 24 Pakistani soldiers, Afghan officials said Sunday. The account challenges Islamabad’s claims that the attacks, which have plunged U.S.-Pakistan ties to new lows, were unprovoked. AP/PTI(AP11_28_2011_000007B)
