A band of Taliban insurgent fighters is claiming responsibility for kidnapping Canadian journalist Mellissa Fung, who was freed in Kabul on Saturday, four weeks after she had been abducted by two armed men, the Globe and Mail reported. The CBC journalist, who had been reporting mostly from the NATO military base in Kandahar, was on her way to report on a Kabul-area refugee camp when she was kidnapped on Oct. 12. News of the abduction had been kept secret as per a media embargo requested by CBC. After her release, Prime Minister Stephen Harper thanked everyone in Afghanistan and Canada "who worked so tirelessly to ensure this outcome." Canadian officials are denying reports that Taliban prisoners were swapped for the reporter, or that a ransom was paid.
