The United States plans to unseal charges soon against a Libyan man suspected of assembling the bomb that blew up a US airliner over Lockerbie, Scotland, in 1988, US newspapers reported on Wednesday. Al Jazeera reports that the whereabouts of the suspect, Abu Agila Mohammad Masud are unknown, but he was imprisoned in Libya at one point for unrelated crimes and is believed to currently be being held by the Libyan authorities, and US authorities are now seeking his extradition to stand trial in the United States. To this day, the bombing on December 21, 1988 remains the deadliest attack ever by a hardline group perpetrated on British soil.
