PESHAWAR, PAKISTAN, DEC. 23 -- A British cameraman on assignment in Afghanistan for the British Broadcasting Corp. apparently has been killed by Afghan guerrillas, his wife said today.

Andy Skrzypkowiak, 36, was last seen in October near Kantiwar in the northeastern province of Nuristan, shortly after he had been detained by a commander of Hezb-i-Islami, one of seven Afghan resistance groups based here.

Hezb commanders have said previously that they had instructions to confiscate films and materials from journalists covering the war with other rebel groups.

The leader of Hezb, Gulbuddin Hekmatyar, reportedly said recently that only journalists with documents from his organization would be allowed to enter Afghanistan. Observers attribute the Hezb hostilities to traditional intergroup rivalry.

Skrzypkowiak's wife, Chris Gregory, in Pakistan to investigate her husband's whereabouts, said reports indicated that he probably was dead.

She said that a witness passing through the Kantiwar area saw a foreigner fitting her husband's description being pursued by four members of Hezb-i-Islami. The witness said he later heard shots.

On Dec. 14, a group of Hezb resistance fighters was arrested in the town of Mardan, in Pakistan's North West Frontier Province. Two of the men reportedly have been identified by the witness.
