The Libyan government said Wednesday it will stop paying armed groups from the 2011 uprising unless they sign up to join the security forces by the end of the year.

The government will "stop paying any premium or reward after" December 31, a deadline for the "dissolution of the armed groups and their integration into the army or the police", said a statement.

Slain Libyan leader Moammar Gadhafi's son Seif al-Islam, wanted by the International Criminal Court, has appeared on television from his cell in a prison southwest of the capital.

He gave brief answers to three questions from a journalist for Alassema television late Tuesday, confirming that he was allowed to receive visitors and was in good health.

Two people were wounded in a gunfight that broke out at a Tripoli checkpoint between former rebels who fought to overthrow Moammar Gadhafi, a security official said Tuesday.

The fighting erupted after security forces stopped a car with tinted windows carrying members of a brigade that had fought in the city of Misrata during the 2011 uprising, according to Hashem Besher, head of a unit of former rebels under the authority of the interior ministry.

An army officer was killed on Sunday in the restive Libyan city of Benghazi when a bomb placed under his car exploded, a security forces spokesman told Agence France Presse.

The blast also seriously wounded the officer's wife and two children, who were with him at the time.

Forty-eight Egyptian illegal immigrants who went missing in the desert of eastern Libya at the start of the week were found by the Libyan air force on Friday, a security official said.

Dozens of Egyptians entered Libya but were abandoned on Monday by smugglers on the desert road between Tobruk and Ajdabiya.

Three people have been shot dead in the eastern Libyan of Benghazi, where security forces also found the body of a kidnapped banker, security sources said Tuesday.

Benghazi was the cradle of the revolt that toppled dictator Moammar Gadhafi in 2011, but since the strongman's ouster it has been rocked by a wave of deadly bombings and shootings.

Two Egyptians were found dead and dozens have gone missing in eastern Libya after they "illegally" crossed into the country, Egypt's foreign ministry said Tuesday.

A Libyan security source confirmed the group entered Libya secretly but were abandoned by smugglers on the desert road between Tobruk and Ajdabiya.

Gunmen attacked a central bank van in Libya on Monday, stealing $54 million (40 million euros), in the latest sign of growing lawlessness since the 2011 overthrow of Moammar Gadhafi.

The official LANA news agency said "10 heavily armed men" had made off with the funds, which were destined for the Libyan central bank branch in the central city of Sirte, and had been flown there from Tripoli.

A bomb exploded early Monday outside a reception hall in the restive eastern Libyan city of Benghazi, damaging the building without wounding anyone, security officials said.

"Unknown assailants on Monday morning threw an explosive device at a building housing a reception hall," security forces spokesman Colonel Abdallah al-Zaidi said.

A Libyan court indicted around 30 senior Moammar Gadhafi aides, including the dictator's son Seif al-Islam, on Thursday for a raft of alleged offenses during the 2011 revolt, prosecutors said.

"The court ordered they stand trial on the main charges against them dealing with the repression of the 2011 revolt," prosecutors' office spokesman Seddik al-Sour said after the hearing.
