Italian aid worker Clementina Cantoni has been released nearly a month after being taken hostage in Afghanistan, according to the Afghani Interior Ministry. "She has just been released," said a ministry spokesman adding she was "fine." Cantoni, who works for aid agency Care International, was abducted on May 16 by gunmen who forced her out of her car in central Kabul. She has been in Afghanistan since September 2003, supporting more than 10,000 widows and their children. Hours before her release was announced, hundreds of schoolgirls in the Afghan capital, Kabul, handed out nearly 3,000 stickers calling for Ms Cantoni to be freed. No details about her release were immediately provided.
