Libyan rebels are stopped by Gaddafi's forces 100 km east of the the city of Sirte.

Forces loyal to Muammar Gaddafi are resisting an advance by Libyan rebels towards the embattled Libyan leader's hometown of Sirte in the fiercest clashes since the start of a sweeping offensive that has brought a string of coastal towns under opposition control.

The rebels, backed by international coalition air strikes, have advanced largely unchecked since Friday but claims in Benghazi, the rebel's eastern stronghold, earlier on Monday that Sirte had also fallen were premature.

Opposition fighters are now engaged in clashes about 100km east of the city, with pro-Gaddafi forces shelling their front lines.

Fighting is ongoing at Nawfaliya, about 180km east of Sirte, where opposition forces say they have come upon a heavily mined road. Pro-Gaddafi forces have dug into positions near the front line, and are shelling opposition fighters.

"Sirte will not be easy to take. Now, because of NATO strikes on [the government's] heavy weapons, we're almost fighting with the same weapons," said General Hamdi Hassi, an opposition commander from the city of Bin Jawad.

"Part of the city is under rebel control and the other part is under the control of forces loyal to Gaddafi," a spokesman told the Reuters news agency.

Nine people were killed overnight by snipers and shelling by pro-Gaddafi forces, according to a doctor there, while a resident told Reuters that 24 people had been wounded in mortar attacks by government forces.

A Libyan government spokesman claimed Misurata had been liberated.
