ISLAMABAD, PAKISTAN — A crucial land route for military supplies for Western troops in Afghanistan was reopened Friday by Pakistani authorities, three days after being closed because of

fighting between the Pakistani army and Islamic militants. But the reopening of the historic Khyber Pass was unlikely to mark an end to bold attacks by militants that have plagued the route,

making shipments of NATO materiel increasingly untenable for the last two months. About three-quarters of the supplies bound for U.S. and NATO troops in Afghanistan pass through Pakistan.

With the expected deployment of as many as 30,000 additional American troops to Afghanistan in coming months, the security of the supply route is likely to become an even more pressing

triumphantly raising the Taliban banner over captured Humvees has become emblematic of the fast-deteriorating situation in and near Peshawar, the principal city in Pakistan’s troubled

northwest. Taliban fighters have gained a solid foothold on the city’s outskirts, where girls schools have been burned, music and video shops blown up and women ordered to veil themselves or

face death. Previous efforts by Pakistani troops to subdue militants in the tribal area known as the Khyber agency have proved short-lived. During a similar offensive in the Khyber agency

in June, militants simply decamped before the troops arrived, and filtered back once the soldiers pulled back. Pakistani officials said artillery and helicopter gunships blasted militant

hide-outs during this week’s operation, which began Tuesday. But some residents said there was little sign of any direct confrontation between the insurgents and army troops. Although the

militants have repeatedly struck Pakistani cities with suicide attacks, there is little public support for army operations such as the Khyber offensive. Reflecting the weak civilian

government’s awareness of the mission’s unpopularity, the Pakistani army did not issue announcements about troop activities, leaving that to local officials. The government, led by the

Pakistan People’s Party of slain former Prime Minister Benazir Bhutto, is also facing rising public anger over a wave of missile strikes in the tribal belt, believed to be carried out by

unmanned U.S. drones. Dozens of such raids have taken place since August, including back-to-back strikes Thursday and Friday in South Waziristan. Friday’s strike, which hit an abandoned

girls school being used by insurgents, reportedly killed three people. Militant leaders are the targets of these missile strikes, and officials say scores of insurgents have been killed in

the wave of attacks. But no top-level Al Qaeda or Taliban commanders have been among the dead. Friday’s reopening of the mountain pass came amid continuing fighting elsewhere in Khyber, well

away from the route. Many of the most damaging attacks have come on the hundreds of trucks that routinely halt for days at terminals on the edge of Peshawar, waiting for permission to

proceed. Last month, in one particularly brazen strike, hundreds of vehicles parked at truck stops were destroyed. Militants had previously taken to hijacking trucks as they slowly transited

the winding roads. In November, more than a dozen vehicles carrying military supplies were hijacked in a single incident within view of a post manned by Pakistani paramilitary troops. In a

sign of the continuing danger, the region’s top administrator, Tariq Hayat Khan, told journalists in Jamrud, the main town in Khyber, that the route would be open only from 11 a.m. to 4 p.m.

Khan said that the Khyber operation had turned up several weapons caches that included heavy machine guns and rocket launchers, and that nearly four dozen militants had been captured. But

local witnesses said many of the insurgents had fled into the neighboring Mohmand tribal area rather than face the troops. -- [email protected] Special correspondent Zulfiqar Ali in
