A London newspaper Friday quoted sources close to the public inquiry into the 1988 Pan Am Flight 103 bombing as saying they have proof that Libya was responsible.

The Independent quoted the unidentified high-level sources as saying the conclusion was based on analysis of a detonator fragment found in a field close to the southern Scottish town of Lockerbie. It said the evidence had come to light only in the past three months.The Boeing 747 was blown up over Lockerbie on Dec. 21, 1988 while on its way to New York. All 259 people on board and 11 others on the ground were killed. The flight originated in Frankfurt, Germany, changing planes at London's Heathrow airport.

The Independent quoted the sources as saying the fragment was identical to a Swiss-manufactured fragment found in a radio-cassette bomb seized from two Libyan secret agents arrested at Dakar airport in Senegal in February 1988, 10 months before the Flight 103 attack.
