Coalition airstrikes took out radar sites near Benghazi and hit two navy bases near the capital Tripoli, al Jazeera reported early Tuesday as the international attacks against Moamer Gaddafi's forces continued for a third night, dpa reported.
Loud anti-aircraft gunfire could be heard in Tripoli and broadcast images showed tracer fire over the city.
An al Jazeera correspondent reported two loud explosions and said two large fires appeared to have broken out in the city's harbour.
"We could see an area of the port on fire, substantially on fire, two big blazes. We saw fire engines racing along the coastal road," reporter Anita McNaught said.
"This evening seems to have been about targeting seaborne military assets of Gaddafi's army, but also we are given to understand (there was) an attack on the airport at Sirte."
The airport in Gaddafi's hometown Sirte and in the city of Sebha had also been attacked, Libyan officials told the broadcaster, saying that civilians had been killed.
The airstrikes to enforce a no-fly zone over Libya began Saturday.
