What to know: US court hearing held for alleged Lockerbie bombmaker

A US judge has scheduled a hearing in Washington, DC, regarding Abu Agila Mohammad Mas’ud Kheir Al-Marimi, a former Libyan intelligence official accused of participating in the 1988 Lockerbie bombing. Federal prosecutors have accused Mas’ud of delivering the bomb that exploded on Pan Am Flight 103, killing 259 people. The trial, which was set to begin last week, has been postponed due to the discovery of new evidence, allowing Mas’ud's defense team time to review it.
