Rival militias clashed in the Libyan capital Tripoli on Wednesday and at least five people were killed and 20 wounded, the health ministry said, splintering a four-month-old, UN-brokered ceasefire, Reuters reports.
Armoured vehicles could be seen in southern Tripoli where militia groups had fought for a month until September, part of the widespread factional conflict plaguing Libya since the 2011 uprising that toppled Muammar Gaddafi.
A United Nations-engineered ceasefire agreed then had managed to hold for the most part until now.
But on Wednesday a militia known as the 7th Brigade, or Kaniyat, and a collection of factions called Tripoli Protection Force fell back into fighting in the same southern district.
The 7th Brigade and some allied groups triggered the August fighting in a bid to challenge the dominance of four “super militias”, including the Tripoli Protection Force, in the streets of the capital.
The UN mission in Libya warned in a statement against any breach of the ceasefire deal.
“Any party initiating a confrontation will be held fully responsible,” it said.
The internationally-recognized government in Tripoli, backed by the United Nations, has been working on a new security plan since the ceasefire deal but achieved little as Libya, long a major oil producer, lacks a national police force or army.
