Lockerbie anniversary: Memorials held for victims

Memorial events have been held across the UK to mark the 25th anniversary of the Lockerbie bombing.

Libyan Abdelbaset al-Megrahi was the only person jailed for the atrocity, which killed 270 people. But the legitimacy of his conviction has been questioned by some of the victims' families.

The UK, US and Libyan governments have vowed to work together to reveal "the full facts" of the attack on 21 December 1988.
