Pakistan protests over border village raid
Updated
Pakistan has summoned the US ambassador to protest against a raid on a Pakistani border village that officials say left 20 people dead.
The pre-dawn helicopter-borne ground assault on the village of Angor Adda in the South Waziristan region is the first known incursion into Pakistan by US-led troops since the invasion of Afghanistan in 2001.
There have, however, been numerous missile strikes on militants in Pakistan, launched allegedly by US-operated pilotless drone aircraft.
Pakistan is a US ally in the unpopular campaign against terrorism, but it rules out incursions by foreign troops into its terrority.
The US says al Qaeda and Taliban militants are based in sanctuaries in northwest Pakistan from where they orchestrate attacks into Afghanistan and plot violence in the West.
