Moslem rebels have taken parts of the provincial capital Takhar, the second major town in northern Afghanistan to be wrested from government control in the vacuum left by the pullout of Moscow's troops, Soviet and diplomatic sources said Wednesday.

A Western diplomat and a Soviet source confirmed reports by the Pakistan-based resistance that its fighters had launched an assault on Takhar, but they differed on how much of the capital of Taloquan Province fell to the guerrillas.The diplomat quoted "multiple Afghan sources" as saying the invaders were in control of the town of 10,000 people more than 40 miles east of Kunduz, the neighboring provincial capital that was in rebel hands for about four days after an Aug. 12 attack.
