Libyan leader Muammar Gaddafi is appealing to US President Barack Obama to halt the NATO operation to protect opponents of his regime.
In a letter to Obama obtained by The Associated Press, Gaddafi implores Obama to stop what he called an "unjust war against a small people of a developing country."
A US official confirms that the US thinks the rambling, three-page letter is authentic.
In the letter, sent on Wednesday, Gaddafi says his country had been hurt more morally than physically by the NATO campaign, and a democratic society could not built through missiles and aircraft.
He also repeated his claim that his foes are members of al-Qaeda.
Gaddafi addresses Obama as "our son" in the letter and says he hopes Obama will win re-election in 2012.
