Shortly after the daughter of Colombia's ambassador to Canada was abducted, armed men kidnapped a journalist whose family owns the country's leading newspaper and shot his chauffeur to death, police said.

It was not immediately known if drug traffickers, who are at war with the government, were responsible for Wednesday's abductions.The newspaper La Prensa reported Wednesday that the Medellin cocaine cartel had abducted the six journalists missing since Aug. 30.

It said the six were taken in a bid to pressure the government into negotiating the terms under which drug traffickers could be tried in Colombia.
