The man suspected of building the bomb that downed Pan Am flight 103 over Lockerbie in 1988 - killing 270 people - has pleaded not guilty, a US court has heard.
Abu Agila Mohammad Mas'ud Kheir Al-Marimi is alleged to have helped make the bomb which killed all 259 passengers and crew on board the jumbo jet bound to New York from London on December 21, 1988.
Another 11 people were killed in Lockerbie when wreckage destroyed their homes, in what remains Britain's deadliest terrorist attack.
