KABUL, Afghanistan (AP) — The Taliban ambushed a peace convoy in western Afghanistan and abducted 26 activists, members of a peace movement, a police spokesman said Wednesday.

The insurgents staged the ambush in the district of Bala Buluk in Farah province on Tuesday. The Taliban forced the six-vehicle convoy to a halt, then got into the cars and drove them and the activists to an unknown location, said the provincial police spokesman Mohibullah Mohib.

According to Mohib, a police operation is underway to locate and free the activists whose convoy was going village-to-village to rally for peace.

However, Bismillah Watandost of the People’s Peace Movement of Afghanistan, to which the activists belong, said that 27 of their members were abducted by the Taliban in the Farah assault. The different figures could not immediately be reconciled.

The Taliban, who have been active in Farah, have not claimed responsibility for the abductions. However, Watandost also said that tribal elders in the province immediately launched an effort to negotiate with the Taliban to release the abducted activists. He added that phone lines were down in the region, making communication and getting information from the area difficult.
