BOGOTA, May 23 (AFP) - Colombian authorities have found new leads as to the whereabouts of Senator Piedad Cordoba, kidnapped last week, and the government will pay up to 300,000 dollars for information on the case, the head of the secret service said Sunday. The secret service, the army and the police "are coordinating their work on new leads found in the last few hours as to the senator's location," Colonel German Jaramillo told reporters here. He declined to elaborate on where they were searching, but said the government would pay between 60,000 and 300,000 dollars for information about where she was taken. "We're offering a reward that we'll pay in accordance with the information's credibility," he said. The right-wing Self-Defense Units of Colombia (AUC) claimed responsibility for kidnapping Cordoba, who strongly supports peace talks between the government and leftist rebels. Cordoba was kidnapped in a daring hospital raid on Friday in Medellin, a city some 450 kilometers (280 miles) northwest of here. Her husband said her family has not received any other information about her and does not know whether she is alive. President Andres Pastrana condemned the kidnapping in a statement issued after meeting with several cabinet ministers Saturday, saying, "No kidnapping is justified and cannot be accepted."
