The United Nations says an attack on residential neighbourhoods in Libya's capital Tripoli could amount to a war crime.
At least seven civilians were killed and 20 injured during shelling on Tuesday.
On Wednesday, funerals were held in Tripoli's Martyrs' Square for those who died in the rocket attacks by forces loyal to renegade military leader Khalifa Haftar.
Soldiers loyal to Haftar and forces belonging to the internationally recognised government are fighting for control of the city.
Al Jazeera's Mahmoud Abdelwahed reports from Tripoli.
