Loud explosions have rocked the Libyan capital Tripoli, briefly putting three TV stations off the air, as NATO jets overflew the city. Reports say Libyan Television, Jamahiriya and Shababiya were off air for about half an hour following the blasts shortly after midnight. Forces loyal to the Libyan leader yesterday bombarded areas of the western city of Misrata, despite the regime saying it had halted attacks to allow local tribes to negotiate with rebels. At least six people were reported killed in the latest bombardment, which reportedly hit the city centre and three residential districts. According to a report although pro-Gaddafi forces encircled Misrata, their forces inside the city were themselves surrounded by rebel fighters. Human rights groups say more than 1,000 people have been killed in Misrata and many more wounded. Ships have been ferrying the wounded to hospitals in Benghazi. Meanwhile, Libya is seeking Russia's mediation for a political settlement of the armed conflict in the country.
