Pakistani troops backed by helicopter gunships killed about 35 militants on Saturday in attacks on militant hideouts in the northwestern Khyber Pass region, a spokesman for the paramilitary Frontier Corps said, according to Reuters. The airstrikes come as troops continue mopping up militant positions in the northwestern Swat valley, where the military says more than 2,000 militants have been killed since an offensive was launched in April. Troops began a new operation in the Khyber this week against militants, including some who had fled from the Swat offensive.
