The West warned Libya on Thursday that political instability is hampering international efforts to provide assistance to the deeply-divided country.

Italy's new Foreign Minister Federica Mogherini told Libyan Prime Minister Ali Zeidan and a large delegation of foreign ministers in Rome that "international partners are ready to help Libya", but the "uncontrolled circulation of arms" in the country was creating difficulties.

A son of late dictator Moammar Gadhafi was extradited Thursday from Niger to Libya, where he is accused of murder and repression during the 2011 uprising that ended his father's rule.

"Saadi Gadhafi was handed over to the Libyan government on March 6. He has arrived in the country and is in the custody of the judiciary's police," a government statement said.

The son of the commander of Libya's special forces was freed Wednesday, more than one month after being kidnapped in the eastern city of Benghazi, a military spokesman told Agence France Presse.

"The son of Wanis Abu Khamada has been released. He is on his way home," special forces spokesman Milud al-Zwei said.

Libya decided rehabilitated Tuesday the family of the late king Idriss, who was overthrown by Moammar Gadhafi, himself toppled and killed in a 2011 uprising after four decades in power.

A decree issued by the government stipulates that the heirs of Idriss al-Senussi will regain their Libyan nationality and recover property confiscated by Gadhafi.

Two separate attacks in the restive eastern Libyan city of Benghazi left three people dead, including an air force officer, a security official said Tuesday.

Colonel Adem Faraj al-Abdelli was found shot dead in his car near a cemetery in the eastern city of Benghazi, the official said on condition of anonymity.

Libyan authorities vowed Monday to stick to the "democratic path" in the face of mounting lawlessness in which two MPs were shot when protesters stormed the country's transitional parliament.

On Sunday, two members of the General National Congress (GNC) were shot and wounded as armed protesters stormed their building in Tripoli. In a separate incident, a French engineer was killed in the restive eastern city of Benghazi.

Two Libyan politicians on trial over a cartoon said to be offensive to Islam on Sunday had charges that could have led to the death penalty dismissed, their lawyer said.

"The court gave its verdict. It decided on a dismissal of the three main charges" which carried a possible death penalty in the case of a conviction, lawyer Abdelmajid al-Mayet said.

Dozens of protesters on Sunday stormed Libya's interim parliament, the General National Congress, with some of them rampaging through the building, witnesses said.

Two members of the parliament were shot and wounded when protesters stormed the building, said the speaker of the assembly.

Gunmen shot dead a French engineer in the eastern Libyan city of Benghazi Sunday, a medical source said, and France's foreign minister demanded that the attackers be brought to justice.

The killing was the latest in a string of attacks and kidnappings targeting foreigners in the North African nation, which has been awash with guns since the 2011 uprising that toppled long-time strongman Moammar Gadhafi.

Gunmen dispersed a sit-in protest outside Libya's interim parliament overnight, firing in the air and detaining demonstrators, witnesses said on Sunday.

"Armed men came firing in the air and they set fire to a tent set up by demonstrators" in front of the General National Congress (GNC), Libya's highest political authority, protester Milad al-Arbi said.
