“I can tell you when you wander through this town there are very few residents here, most of them have fled, it”s like a ghost town.
Tony Birtley, Al Jazeera’s correspondent in Benghazi, said opposition forces were “stuck” and unable to move forward.
“I think the reason for that is partly because they”re disorganised, partly because they don”t have the weapons and partly because Gaddafi’s forces are very strong and have a lot of hardware,” he said.
Al Jazeera has also heard that Gaddafi’s forces have stepped up their attacks on the town of Zintan, west of the capital Tripoli.
A loud explosion was heard in Tripoli early on Thursday, and smoke could be seen rising from an area where a military base is situated.
“We heard another explosion just now. We see smoke rising. There are people on rooftops. It seems to be in a military area near the engineering college [in the Tajoura area],” one resident told Reuters news agency.
Libyan state television said Western planes had struck in Tripoli and in Jafar, southwest of the capital.
“Military and civilian targets were attacked by colonialist crusaders,” the report said.
The US military said 14 Tomahawk missiles were launched overnight, while the US Africa Command in Germany said coalition forces also dropped bombs on targets.
Government officials have accused coalition forces of killing dozens of civilians,and some journalists were taken to a hospital early on Thursday morning and shown 18 charred bodies, which the government said were military personnel and civilians killed in the air strikes, Reuters reported.
But the US military officials deny any civilians have been killed in air strikes.
Undeterred by raids
The US military said it had successfully established a no-fly zone over Libya’s coastal areas and had moved on to attack Gaddafi”s tanks.
The allies flew 175 sorties in 24 hours, and the US flew 113 of those, a US commander said.
Gerard Longuet, the French defence minister, said France had destroyed about 10 Libyan armoured vehicles over three days.
However, Gaddafi’s tanks have rolled back into the town of Misurata under the cover of darkness, residents and opposition fighters said, resuming their attack after their guns were silenced on Wednesday by Western air raids.
The city, around 200km east of Tripoli and home to a major oil refinery, remains the last of opposition hold-outs in the west.
“Government tanks are closing in on Misurata hospital and shelling the area,” a doctor in Misurata told Reuters on the phone before the line was cut off.
