Lockerbie bombing victims remembered 25 years on Memorial events have taken place to mark the 25th anniversary of the Lockerbie bombing, which claimed the lives of 270 people. Wreaths were laid at Dryfesdale Cemetery in the Scottish town and a service took place in a local church. The US, UK and Libyan governments have released a joint statement vowing to cooperate to reveal the "full facts" of the bombing of Pan American flight 103. Many questions remain unanswered over the attack. Libyan Abdelbaset al-Megrahi was the only person convicted and was released from prison in 2009 on humanitarian grounds. He was diagnosed with prostate cancer and died in Tripoli last year protesting his innocence. All 243 passengers and 16 crew, the majority of whom were US citizens, on board the flight from London to New York were killed when the plane exploded over Scotland. A further 11 people were killed when wreckage hit their homes in Lockerbie.
