BENGHAZI, Libya (Reuters) - Battles raged on several fronts in Libya on Friday after a night of heavy bombardment in Tripoli, combatants and residents said, despite the threat continued fighting poses to efforts to stop the coronavirus pandemic.

Serious warfare resumed this week after a comparative lull in recent weeks, defying international calls for calm to allow Libya's fragmented and overstretched health system to prepare for any spread of the coronavirus.
