The Libyan oil terminal town of Brega has been targeted with air strikes, sources in the town said.
The strikes come a day after clashes between rebels and government troops in the town in which 14 people died.
Forces loyal to Libyan leader Muammar Gaddafi took control there on Wednesday morning but were forced out by opposition fighters later in the day.
Col Gaddafi has lost control of the eastern half of Libya during two weeks of unrest but has vowed to fight on.
In a televised speech on Wednesday, Col Gaddafi also said that thousands of Libyans would die if Western forces intervened.
