September 11 hijackers granted US visas in immigration blunder

The American government tonight faced embarrassment when a flight school where two of the September 11 hijackers trained received a letter saying they had been approved for visas.

Huffman International flying school was told former students Mohammed Atta, the ringleader of the September 11 hijacks, and fellow terrorist Marwan al-Shehhi had been allocated official student visas.
