BAGRAM AIR BASE, Afghanistan, September 16 (IslamOnline & News Agencies) - Ten rockets were fired at two U.S. bases in the eastern city of Khost overnight Monday, September 16, as two U.S. special forces soldiers were injured by an explosive device in eastern Afghanistan, news agencies reported.

There were no immediate reports of casualties resulting from the rocket attacks, the Pakistan-based Afghan Islamic Press (AIP) said.

U.S. spokesman Lieutenant Colonel Roger King said the explosion, which injured the soldiers occurred Sunday, September 15, in Kunar province between Assadabad and Jalalabad. A second device was found nearby, reported Agence France-Presse (AFP).

"Two soldiers were medically evacuated by helicopters, one for wounds and one for possible hearing loss," King said, adding one was already back on duty.

He gave no details of the operation in which the two were taking part.

Unconfirmed reports say fugitive former Afghani Prime Minister Gulbuddin Hekmatyar is in Kunar.

Last week, Hekmatyar called for Jihad (holy struggle) to expel U.S. invading forces from Afghanistan, according to the AIP. However, he denied involvement in a massive car bomb blast in Kabul on September 5.

King also said U.S. troops operating in the eastern province of Khost recovered a cache of weapons including several hundred 107mm rockets and one launcher.

U.S. bases in Khost and neighboring provinces regularly come under rocket attack but there are few casualties.

The AIP said the latest rocket attacks on Khost airport and Sarabagh were the most intense since U.S. forces were deployed in the area. It said it was not known whether the rockets landed inside or outside the two bases.

American helicopters arrived and fired flares, the agency said.

Almost 1,000 U.S. troops were deployed in nearby Paktia province as part of Operation Champion Strike, the latest offensive against Al-Qaeda and Taliban resistance diehards thought to be holed up in the area.
