EDINBURGH, Scotland (AP) - Britain's government said it has warned Libya that any celebration of the anniversary of the release from jail of the Lockerbie bomber would be offensive and insensitive to the families of the mainly U.S. victims of the
attack.

Abdel Baset Al-Megrahi is the only person convicted in connection with the 1988 bombing of Pan Am Flight 103 above
Lockerbie, Scotland, which killed 259 people onboard - mostly Americans - and 11 on the ground.

He was ordered in 2001 to serve 27 years in jail, but he was freed on Aug. 20 of last year on compassionate grounds, as he has cancer.

Al-Megrahi returned to Libya.

In a statement issued Friday, Britain's Foreign Office said any celebration of al-Megrahi's freedom would be "tasteless, offensive and deeply insensitive."
