Libyan forces loyal to Muammar Gaddafi are waging a bloody operation to keep him in power, with residents reporting gunfire in parts of the capital Tripoli and other cities, while other citizens, including the country's former ambassador to India, are saying that warplanes were used to "bomb" protesters.
Nearly 300 people are reported to have been killed in continuing violence in the capital and across the North African country as demonstrations enter their second week.
Fighter jets bombed portions of the city in fresh attacks on Monday night. The bombing focused on ammunition depots and control centres around the capital.
Helicopter gunships were also used, they said, to fire on the streets in order to scare demonstrators away.
Several witnesses said that "mercenaries" were firing on civilians in the city, while pro-Gaddafi forces warned people not to leave their homes via loudspeakers mounted on cars.
Residents of the Tajura neighbourhood, east of Tripoli, said that dead bodies are still lying on the streets from earlier violence. At least 61 people were killed in the capital on Monday, witnesses told Al Jazeeera.
Protests in the oil-rich African country, which Gaddafi has ruled for 41 years, began on February 14, but picked up momentum after a brutal government crackdown following a "Day of Rage" on February 17. Demonstrators say they have now taken control of several important towns, including the city of Benghazi, which saw days of bloody clashes between protesters and government forces.
There has been a heavy government crackdown on protests, however, and demonstrators at a huge anti-government march in the capital on Monday afternoon said they came under attack from fighter jets and security forces using live ammunition.
"What we are witnessing today is unimaginable. Warplanes and helicopters are indiscriminately bombing one area after another. There are many, many dead," Adel Mohamed Saleh said in a live broadcast.
"Anyone who moves, even if they are in their car, they will hit you."
Ali al-Essawi, who resigned as Libyan ambassador to India, also told Al Jazeera on Tuesday that fighter jets had been used by the government to bomb civilians.
He said live fire was being used against protesters, and that foreigners had been hired to fight on behalf of the government. The former ambassador called the violence "a massacre", and called on the UN to block Libyan airspace in order to "protect the people".
