Cairo: Algerian authorities have decided to move the family members of Libyan leader Muammar Gaddafi to the capital Algiers over safety concerns, a website reported.

Gaddafi's wife Safia, daughter Aisha, and two sons - Muhammad and Hannibal arrived in the Algerian southeastern border zone on August 29.

Gaddafi's family members will be under house arrest in Algiers, reports said.

They were taken to Algeria by a team of 35 former South African Special Forces operatives, who were paid $15,000 each for the operation, reports said.

The paper cited an unidentified person who was asked to take part in the mission, but he declined.

The rebel-led National Transitional Council (NTC) is demanding the extradition of Gaddafi's family from Algeria.

Gaddafi's daughter Aisha has given birth to a girl since arriving in Algeria. Media reports suggested her pregnancy was a major factor in the decision by the Algerian authorities to grant the group refuge.
