A suspected al Qaeda-trained militant who was shot dead Thursday after a siege in Toulouse was on the U.S. no-fly list, a U.S. intelligence official confirmed Thursday.

The official said Mohammed Merah had been on the list for some time, one reason being that he had attended an al Qaeda training camp.

Merah, 23, was wanted in the killings of three French paratroopers, a rabbi and three children ages 4, 5, and 7. The shootings began March 11 and ended Monday with the slaying of the rabbi and the children at a Jewish school in Toulouse.

Merah died Thursday during a police raid on his Toulouse apartment after a standoff that had lasted more than 31 hours, Paris prosecutor Francois Molins said.
