A spokesman for kidnappers holding an American captive in Pakistan says the deadline to negotiate for his life has been extended a "few days."

U.N. official John Solecki was abducted on Feb. 2 in Quetta, a major city in the southwest near the Afghan border.

On Friday, his kidnappers threatened to kill him within 72 hours and issued a 20-second video of the blindfolded hostage.

Shahak Baluch, who claims to speak for the little-known Baluch United Liberation Front, said in a call to the Quetta Press Club that the deadline has been extended after appeals from "some international organizations."
