The mother of an American UN official kidnapped nearly three weeks ago in Pakistan has urged the public to help secure his release, in an audiotaped message released Saturday by the UN. John Solecki, head of the UN refugee agency (UNHCR) office in Quetta, was abducted at gunpoint on February 2 while travelling to work. His driver was killed in the ambush. It was the most high-profile Western kidnapping in Pakistan since 2002, when US journalist Daniel Pearl was snatched and beheaded by Al-Qaeda militants. "My name is Rose Solecki. The UNHCR worker who went missing in Quetta, John Solecki, is my son. I am appealing to the people of Baluchistan for whatever support they can provide to secure my son's safety and freedom," the 83-year old woman said.
