With a White House meeting, talks at a think-tank, and interviews with newspapers, Islamists unshackled by the Arab Spring are launching a new charm offensive to reassure a nervous Washington.

The rise to power of elected Islamists in Tunisia, Egypt and elsewhere has alarmed many Americans, who fear the emergence of Iran-style theocracies that would deny the rights of women and minorities and antagonize Israel.

Seif al-Islam, son of slain leader Moammar Gadhafi, will be moved next week to Tripoli and has agreed to take a lawyer, Libya's representative to the International Criminal Court said Saturday.

"Seif al-Islam will be transferred from his prison in Zintan to an official prison in the capital Tripoli before the end of the (coming) week," Ahmed Jehani told Agence France Presse, declining to give an exact date for security reasons.

The global police agency Interpol issued alerts Thursday seeking the arrest of two senior officials in late Libyan strongman Moammar Gadhafi’s regime on suspicion of torture and kidnapping.

A statement from the France-based body said Libya had requested assistance in detaining two officials identified as former interior minister Al-Senussi Alozyre, 63, and his former deputy Naser al-Mabrouk, 60.

Libyan troops managed to uphold a ceasefire between rival groups in the west of the country after three days of deadly clashes, residents told Agence France Presse on Thursday.

"The fighting has stopped and the army is implementing a ceasefire," said Doctor Shukri al-Arabi, who runs the sole clinic of Zuwarah, 100 kilometers (60 miles) west of Tripoli.

Seif al-Islam, the son of slain Libyan leader Moammar Gadhafi, has been attacked in detention in Libya, a lawyer from the International Criminal Court said on Thursday.

"Gadhafi has been physically attacked," ICC defense official Xavier-Jean Keita said in a statement accusing Libyan authorities of depriving the country's onetime favorite son of his fundamental rights.

Fresh fighting erupted in western Libya on Wednesday, killing at least two people near the border with Tunisia, a hospital official said.

"The situation is once again critical," said Shukri al-Arabi, who runs the only hospital of Zuwarah, a coastal town 100 kilometers (120 miles) west of Tripoli.

Clashes in western Libya have left at least 14 people dead and 80 others wounded in 24 hours, the ruling National Transitional Council said on Tuesday.

"Four people were killed and 35 others were wounded in Zuwarah," 100 kilometers (60 miles) west of Tripoli, near the border with Tunisia, the interim authorities said in a statement published online.

At least 16 people were killed on Saturday in new clashes between the Toubou people and Arab tribesmen in the southern Libyan desert oasis of Sabha, local and medical sources told Agence France Presse.

A doctor at Sabha hospital, treating Arab casualties, said eight people were killed and another 50 wounded in fighting between the early morning and noon. A Toubou tribal source said eight of their people were also killed.

Libya's former Prime Minister Mahmoud Jibril on Saturday expressed concern that the West had abandoned his country after the collapse of Moammar Gadhafi's regime.

"It is a fatal mistake to abandon Libya", Jibril said at a forum organized by public policy institute the German Marshall Fund of the United States.
