Ten days after being seized during a US raid in Tripoli, Abu Anas al-Libi, the alleged architect of al-Qaeda’s bombing of two US embassies in 1998, plead not guilty in a New York courtroom. If convicted, he faces a sentence of up to life in prison.

Appearing in public for the first time since being captured by US forces in Libya earlier this month, Abu Anas al-Libi, whose real name is Nazih Abdul-Hamed al-Ruqai, appeared in a federal court in Manhattan on Tuesday. After spending a week aboard a US Navy ship in the Mediterranean, Mr. Al-Libi, 49, appeared exhausted and frail. Speaking Arabic through a translator, he asked to be addressed by his real name and confirmed that he understood that he had been accused of planning the August 1998 attacks. After denying a series of terrorism charges, that date back twenty years, Mr. Al-Libi entered a not guilty plea through his lawyer. Presiding Judge Lewis Kaplan has adjourned the hearing until 22 October, noting that the suspect must be kept in detention as a flight risk.

In the weeks since the 5 October mission, which simultaneously saw US Commandos attempt to track down a top al-Shabaab commander in Somalia, anger has been rising in Libya over the raid, with many viewing it as a breach of Libyan sovereignty. Although US Secretary of State John Kerry has defended the capture of Mr. Al-Libi, calling him a “legal and appropriate target,” the Libyan government has demanded a full explanation of the raid from the officials in the US. This resulted in Libya’s justice minister summoning the US ambassador to the country for questioning last week. In turn, Libya’s Prime Minister Ali Zeidan has also voiced his concerns, noting that his country was “keen on prosecuting any Libyan citizen inside Libya.” Shortly after being captured, Mr. Al-Libi was taken to a US navy vessel in the Mediterranean. According to reports, Mr. Al-Libi was interrogated by intelligence officials on board the USS San Antonio for a period of a week after his capture. Court details have also indicated that Mr. Al-Libi was not formally arrested until a week after being seized. This has prompted critics in the US to accuse President Barack Obama of continuing controversial detention policies that had been introduced by former President George W. Bush.

Mr. Al-Libi was wanted in connection to the 7 August 1998 bombing of a US embassy in Nairobi and of America’s diplomatic mission in Dar es Salaam. The attacks were carried out when trucks laden with explosives detonated almost simultaneously. More than 200 people died in the Kenyan capital, with at least 11 dead in Dar es Salaam. Thousands others were injured in the bombings. The majority of the victims were civilians.

For the past decade, Mr. al-Libi has been on the FBI’s most wanted list, with a US $5 million (£3.1 million) bounty on his head. He was formally charged with conspiracy to murder, kidnap and maim Americans, to damage and destroy US buildings and property, and to attack US national defence facilities. The charges against him also include discussing a possible al-Qaeda attack against the US embassy in the Kenyan capital, Nairobi, in retaliation for the American military intervention in Somalia. In a 157-page indictment, prosecutors allege that from 1993, he carried out surveillance on the US embassy in Nairobi, Kenya, where he took photographs that were later inspected by Osama bin Laden. The former computer programmer is also alleged to have “reviewed files” concerning possible attacks on Western interests in East Africa.

The second US command raid on 5 October was carried out in southern Somalia however that mission failed to capture its target – Abdukadir Mohamed Abudkadir, a Kenyan al-Shabaab commander who is also known as Ikrima. That raid came in the wake of the attack on the Westgate shopping centre in Nairobi, which left at least 67 people dead, and which was claimed by al-Shabaab militants.
