(Reuters) - Members of Muammar Gaddafi's entourage are putting out feelers to seek a ceasefire or safe passage from Libya, according to U.S. and European officials and a businessman close to the Libyan leadership.

Messages seeking some kind of peaceful end to U.N.-backed military action or a safe exit for members of Gaddafi's entourage have been sent via intermediaries in Austria, Britain and France, said Roger Tamraz, a Middle Eastern businessman with long experience conducting deals with the Libyan regime.

Tamraz said Saif al-Islam Gaddafi, Muammar's eldest son, and Abdullah Senoussi, the Libyan leader's brother-in-law, were the most prominent Gaddafi entourage members involved in seeking ways to end the fighting.

A U.S. national security official, who asked for anonymity when discussing sensitive information, said that U.S. government agencies were aware that Saif al-Islam and Senoussi had been involved in making peace overtures.

The U.S. official, and a European government official who is also following Libyan events closely, said that U.S. and European governments were treating the purported outreach with caution, but not dismissing it out of hand.

Saif must be longing for his days at the LSE.

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
