Ali al-Hassi, the spokesman for Libya's Petroleum Facilities Guard (PFG), the armed group that protects Libya's national oil facilities, has said that the IS group's fighting lines have been broken but they are trying to regroup.
IS attacked Libya's oil crescent including the oil terminal Sidra on January 4 and 5.
Idriss al-Maghrebi of Libya's House of Representatives, has called on the international community to "assume its responsibilities" towards the oil terminal of Sidra, which has been under attack from the IS group since January 4.
The House of Representatives, one of Libya's main political factions, fled to the eastern city of Tobruk in summer 2014 after being forced from Tripoli. Both it and its rival General National Congress have described themselves as Libya's legitimate governments.
Libya's warring factions signed a UN-brokered peace deal in December to form a national unity government.
More reports are emerging that one of the IS car suicide bombers involved in the attack on the Libyan oil port of Sidra on January 4 was a 15-year-old boy from Tripoli.
Libyan journalist Ali Al-Rahqan has posted on Facebook what he says are details of one of the car suicide bombers used by the IS group on January 4 in an attack on the oil terminal of Sidra.
Al-Rahqan claims the suicide bomber was a 15-year-old boy named Abdel Moneim Dwilla, originally from Tripoli.
According to Al-Rahqan, Abdel Moneim's family said the boy had become more religious, telling his mother that he was going to pray at a different mosque because his usual mosque belonged to a Sufi and was therefore "haram" or forbidden for him.
After some time, Abdel Moneim disappeared and his family thought that he had been abducted. But a day or so later, his father was contacted from a strange number and informed that his son was "in the land of the Caliphate," in other words in IS-controlled Sirte.

The Independent reports that police had sent Siddhartha Dhar a letter to his home address six weeks after he had already left for Syria, asking him to "surrender all travel documents" to a London police station.
There are also unconfirmed reports, citing oil terminal sources in Sidra, that the fighting in Sidra has damaged three crude storage tanks belonging to a subsidiary of the Waha Oil Company of total capacity 1.5M barrels.
Sources in Libya's oil terminal Sidra are reportedly saying that the IS group is planning another attack in the oil crescent and that reinforcements are arriving in the town of Bin Jawad to the west of Sidra.
The reports have not been confirmed.
IS attacked Sidra and the nearby Ras Lanuf for two days in a row.
