HIRA, Libya: Forces supporting Libya's internationally recognised government pushed back troops loyal to eastern commander Khalifa Haftar more than 60 kilometres southwest of the capital Tripoli on Tuesday (Apr 23), Reuters reporters said.
The town of Aziziya was fully under the control of the Tripoli forces, with shops reopening after days of fighting, a Reuters team at the scene said.
Haftar's Libyan National Army (LNA), which is allied to a rival government in eastern Libya, mounted an offensive on the capital almost three weeks ago but despite heavy fighting last week it has failed to breach the city's southern defences.
In recent days, forces backing the Tripoli administration have pushed back the LNA in some areas.
But fighting still raged in some southern suburbs on Tuesday, with shelling heard throughout the day even in central Tripoli, residents said.
The Reuters team driving south of Aziziya through villages on the road to Hira saw several burnt-out cars belonging to Haftar's forces and five dead fighters.
The Reuters reporters made it to about 25 kilometres from Gharyan, the forward base for Haftar's offensive to take Tripoli. The town could still be a challenge to recapture as it lies in the mountains starting after Hira.
One tired-looking LNA prisoner sat on the back of a pickup truck. The Tripoli forces had also seized two Soviet-made tanks from the arsenal of former ruler Muammar Gaddafi, one of them heavily damaged.
As the Reuters team was about to leave, rockets were fired nearby from LNA positions.
According to United Nations figures 264 people, including 21 civilians, have been killed since Apr 5 and 1266 wounded, including 69 civilians. About 32,000 civilians have fled their homes for safer areas.
The latest military action could signal the end of Haftar's immediate plans to install himself as ruler of the whole country and ease a dangerous situation that has divided and confounded foreign governments with an interest in Libya.
However, the front remains fluid and his fortunes could change again. Both sides have gained and lost territory within days or even hours.
If a ceasefire is called as demanded by the United Nations, the LNA would have still gained a considerable amount of territory despite.
The North African country has been in a state of chaos since Gaddafi was toppled in 2011 with Western intervention, and the latest flare-up threatens to disrupt oil flows and leave a power vacuum that Islamist militants could exploit.
Libya is also the main departure point for migrants from elsewhere in Africa trying to reach Europe across the Mediterranean, a big concern for European Union nations.
Migrants in a detention facility in Qasr Ben Ghashir district, which has been fought since the start of the offensive, have reportedly seriously wounded in random shooting, the UN migration agency IOM said. It gave no more details.
