WASHINGTON - The?US government has seen no indication that Muammar Gadhafi has left Libya, the White House said on Monday.

"If we knew where he was, we would pass that on to the opposition forces," White House spokesman Jay Carney told reporters when asked about the whereabouts of the fugitive Libyan leader, who has not been seen since rebels took over the Libyan capital Tripoli last week.

Family members of Libyan leader Muammar Gaddhfi arrived on Monday in Algeria, the official APS news agency quoted an Algerian Foreign Ministry statement as saying.

Gaddhfi's wife Safia, his daughter Aisha, his sons Hannibal and Mohammed, accompanied by their children, entered Algeria at 08:45 am local time (0745 GMT) through the Algerian-Libyan border, the statement said.

Algerian officials allowed Gaddhfi's relatives to enter the country via the Tinalcom crossing point in Illizi province on the southeast border, Algeria's Arabic daily Echorouk said on its website.

The Libyan convoy, comprising seven cars with 31 people on board, had been waited for 12 hours by the crossing point before being authorized to enter Algeria, the paper said.

The health condition of Aisha Gaddhfi, who is pregnant in her 9th month, prompted Algeria to let in the convoy in accordance with international treaties, the report noted.
