LONDON (AP) _ Libya's ambassador presented his credentials to Queen Elizabeth II on Tuesday, formally healing a diplomatic breach after 17 years.

Britain suspended relations in 1984 after a London policewoman was killed by gunfire apparently coming from the Libyan Embassy, and Libya refused to cooperate with the investigation.

Britain announced in 1999 that diplomatic ties would resume, after Libya accepted responsibility for the policewoman's death and agreed to hand over two suspects in the bombing of Pan Am Flight 103 over Lockerbie, Scotland.

Libya had been represented by a charges d'affaires.

The new ambassador, Mohamed Abdul Quasim Al-Zwai, a former justice minister, went to Buckingham Palace in the traditional procession of three horse-drawn carriages to present his credentials.
