(CNN) -- Forces loyal to embattled Libyan strongman Moammar Gadhafi launched a new attack on the rebel-held city of Misrata on Wednesday, with anti-government forces reporting intense shelling from three sides of the city.
Thousands of government troops attacked around 6 a.m. (11 p.m. Tuesday ET), with 13 rebels reported dead by evening. Mohamed Mokhtar, a rebel fighter wounded in Wednesday's fighting, accused government troops of infiltrating rebel lines in cars bearing rebel flags.
Dr. Khaled Abu Falgha, a spokesman for Misrata's Hekma hospital, said it was the bloodiest day in a week in the besieged city. More than 1,000 people are believed to have been killed since the fighting began there in February, including 686 registered residents of the city, he said.
Rebel fighters returning from the front lines reported that their defenses were holding up under the onslaught, however.

The assault followed a day of intense bombardment of Libya's capital by the NATO alliance, which intervened in the conflict in March under a U.N. mandate to protect civilians as Gadhafi tried to crush the revolt against him. Libya's government said 60 missiles struck the capital city, killing at least 31 people, including a number of civilians, and wounding dozens more.
NATO Secretary General Anders Fogh Rasmussen reiterated Wednesday that the alliance is doing all it can to avoid civilian casualties. But he told reporters from allied headquarters in Brussels, Belgium, that NATO could continue the airstrikes "for as long as it takes to bring this crisis to an early conclusion."
Rasmussen said NATO bombing has saved lives in Libya, and that the alliance has the resources to extend its military mission for another 90 days past the end of June.
It is time to start planning for what to do after Gadhafi's departure "because Gadhafi's reign of terror is coming to an end," he said.
Pressed by reporters on why airstrikes would be able to dislodge Gadhafi when "the history of the last 30 years" shows that air attacks alone do not win wars, Rasmussen offered no clear answer, saying only, "We have no intentions to put troops on the ground."

The rbels are fighting for a good cause, but Gadhafi do not want the people turns against him, also one thing that is bad there is that the childrens also are soldiers, the help to built guns and all of that, they are not studing!!! that is one of the worst things in that battle.
