French Defence Minister Herve Morin said Friday that the possibility of a terrorist attack on Air France Flight 447 cannot be ruled out.

"We have no right to exclude terrorism," he told journalists, but adding that he had not heard of any threats to the flight or of any group or individual claiming responsibility for bringing down the aircraft.

The Airbus A330-200 airliner with 228 people aboard went missing over the Atlantic Sunday night after leaving Rio de Janeiro to Paris. According to Air France earlier this week, the plane sent out a series of messages showing "multiple technical failure" just before it disappeared.
