WORLD NEWS:20 more plane bombers prepared by al-Qaida: CBS

WASHINGTON: Twenty other young Muslim radicals have been trained to blow up planes by al-Qaida in Yemen, a young Nigerian charged with trying to

blow up a US airliner has told FBI.

Umar Farouk Abdulmutallab, 23, has told FBI that close to 20 other young Muslim men were being prepared in Yemen to use the same technique to blow up airliners, CBS said in an exclusive investigative report.

The Nigerian terror suspect was arraigned on Friday in a Detroit court on charges of blowing up a North West Airlines plane on December 25.

Abdulmutallab earlier pleaded not guilty to six charges arising out of the botched Christmas Day bombing of Northwest Flight 253 from Amsterdam to Detroit.

The Nigerian allegedly stitched two highly explosive substances into his clothes, and tried to detonate them as the plane carrying 290 people approached Detroit. But the device failed to detonate.
