PESHAWAR, Pakistan — Pakistani helicopters and artillery on Friday forced back militants who crossed over from Afghanistan this week and triggered battles that have killed scores of people, an official said. The government demanded that NATO and Afghan troops do more to control insurgents on their side of the long, porous border.
The Pakistani Taliban, the country’s most prominent militant group, claimed responsibility for the incursion in a telephone call to reporters.
Taliban spokesman Ahsanullah Ahsan said between 40 and 50 fighters took part in the raid, much less than the 400 claimed by the government. Regional administrator Ghulam Mohammad Khan said the militants were retreating Friday and under Pakistani attack in one district.
