Bomber Megrahi dies 'but Lockerbie questions remain'

Abdelbaset al-Megrahi, the only person convicted over the 1988 Lockerbie bombing which killed 270 people, has died at his home in Tripoli.

Suffering from cancer, he was freed from jail in Scotland in 2009 on compassionate grounds and returned to Libya.

BBC News Scotland correspondent James Cook reports on the controversy surrounding his release and why the search for the full story behind the bombing goes on.
