The North African country remains gripped in a civil war allowing ISIL to exploit the chaos as they move into new ground, getting ever closer to the country's oil fields.
According to the United Nations, ISIL are "committing gross abuses including public summary executions of individuals based on their religion or political allegiance.
All sides in the Libyan conflict are breaching international law that amounts to war crimes, a report by the UN human rights office and UN support mission in Libya suggests:
"All parties to the conflicts continue to commit violations of international human rights and humanitarian law, and abuses of human rights, including indiscriminate and disproportionate attacks; summary executions and other unlawful killings; arbitrary deprivations of liberty; and torture and other cruel, inhuman or degrading treatment."
The internationally recognized government has been forced to operate from Tobruk on the eastern border with Egypt and its rival self-styled government in Tripoli, which is run by Libya Dawn, a dominant group of Islamists forces.
The UN has so far, failed to broker a peace deal between the groups to form a unity government and end the fighting between the army and the militias. In an interview with Europe 1 radio, French Defense minister Jean-Yves Le Drian said:
"There must be an intra-Libyan accord between these two rival factions, or else Daesh [ISIL] will win."
Drian said it was "urgent" and that "Daesh [ISIL] is taking territory starting from Sirte and seeking to move down towards the oil fields."
Critics of the NATO-led intervention in 2011 to overthrow the country's leader Colonel Gaddafi, have blamed the countries involved — including France and Britain — of leaving the Middle Eastern country in chaos.

The threat from Islamic State militants making dangerous moves into the country continues while warring factions fight on and refugees flee to Europe.
