Cat Stevens = terrorist?

Ted Kennedy and Cat Stevens - both on government watch lists.

United Air Lines Flight 919 from London to Washington was diverted to Maine after the singer's Muslim name, Yusuf Islam, turned up on a "watch list" designed to keep terrorists or their supporters from boarding flights, U.S. officials said.

Islam, 56, took that name when he became a Muslim in the 1970s.

An FBI spokeswoman told CNN the singer's name was only matched to the watch list after the plane had departed London.

While the plane was in flight, the Advanced Passenger Information System flagged Islam's name, a Department of Homeland Security official said.
