Two children have reportedly been killed in shelling on the Libyan capital Tripoli, despite a ceasefire that was meant to come into effect earlier this month.
The internationally recognised government based in the capital said that a stray shell fell near a school.
It accused forces loyal to Gen Khalifa Haftar - the military commander with his power base in eastern Libya - of being responsible.
Recent days have seen renewed heavy fighting between the two sides in several locations.
