Paris: French President Nicolas Sarkozy will propose air strikes on Libyan leader Muammar Gaddafi's command headquarters to EU leaders, a source close to discussions told AFP on Thursday.

At an EU summit on the Libyan crisis, he will propose "striking an extremely limited number of points which are the source of the most deadly operations" by forces loyal to Gaddafi, said the source, who asked not to be named.

The three sites being considered are Gaddafi's Bab Al Azizia command headquarters in Tripoli, a military air base in Syrte, east of Tripoli and another in Sebha in the south, the source added.

Sarkozy's office declined to confirm the claim when contacted by AFP.

"We are not there yet. We are first going to ask for legal authorisation to prevent the use of force by Gaddafi," said an official.

The source said Sarkozy is also in favour of jamming communications systems of forces loyal to Libyan leader Muammar Gaddafi's, which are battling rebels after an uprising against the long-term ruler.

France has seized the initiative in European pressure against Gaddafi. Earlier Thursday it formally recognised the Libyan rebels' opposition national council as the country's legitimate representative.
