A Libyan man charged with making the bomb that brought down Pan Am Flight 103 over Lockerbie, Scotland, in 1988 has entered a plea of not guilty in a Washington court.
US prosecutors allege 71-year-old Abu Agila Mohammad Mas'ud Kheir Al-Marimi built and set the bomb which was placed in a tape recorder and loaded into a suitcase which exploded as the New York-bound plane flew over Lockerbie in December 1988.
