U.S. and Afghan Troops Battle to Control Crucial Route.

ASADABAD, Afghanistan -- American and Afghan troops have killed at least 115 insurgents as part of a tough fight to gain control of a critical corridor and resupply route to a key American base in northeastern Afghanistan, according to Afghan and American military officers. Civilians in the area, as well as American and Afghan soldiers, described an exceptionally intense fight, which was still going on, in which long-range bombers have flown in from as far away as the Persian Gulf emirate of Qatar, the southern Afghan province of Kandahar and Bagram Air Base outside Kabul, the Afghan capital.
