A powerful Soviet-made Scud missile, apparently fired from Kabul, killed nine Afghan guerrillas and wounded 17 in the rebel-controlled border post of Torkham, just 300 yards from Pakistan.

The attack, which took place Wednesday and was reported by the rebels Thursday, was the first time an SS-1 missile has landed so close to Pakistan, since the missiles were delivered to Kabul by the Soviet Union in November. Pakistan harbors the U.S.-backed rebels,The Soviet-backed regime has used the weapons extensively against rebels conducting a 3-week-old operation to capture Jalalabad city, 40 miles west of Torkham, but the guerrillas say the missiles never before caused so many casualties at once.
