Unconfirmed, unverified:

A convoy of six Mercedes cars have crossed from Libya into Algeria, Egypt’s state MENA news agency reported on Saturday, quoting a rebel source.

It was impossible to verify the report and it was not immediately clear who might have been in any convoy, but MENA quoted the source as speculating that senior Libyan officials or Muammar Qaddafi himself and his sons may have fled the country.
