Loud blasts were heard on Tuesday in the Libyan capital of Tripoli, without immediate reports of casualties, Xinhua reported.
The blasts were heard near the residence of Libyan leader Muammar Gaddafi, said local witnesses.
Explosions were also heard in the Bab Al-Azizya district, they said.
It was not immediately clear whether the explosions were fresh air strikes by the West-led coalition forces.
The city has witnessed frequent bombardment over the recent days as the multinational coalition carried out military intervention in the Northern African country.
One administrative building of the residence compound of Gaddafi was destroyed by a missile fired by a Western warplane March 20.
