At least 106 people have been killed in three days of fighting between Daesh (ISIS) loyalists and local tribesmen in Libya's city of Sirte, the Saudi-based broadcaster Al Arabiya reported on Friday citing an unnamed local official.
Most of the dead were members of the Ferjan tribe who refused to pledge allegiance to the radical organization, according to the report.
Daesh insurgents Friday torched a makeshift hospital in Sirte's so-called District No 3, which has been besieged by the militants since Wednesday, Al Arabiya said. No casualties were reported.
The violence erupted after the body of Sirte's prominent Muslim cleric, Khaled bin Rajeb, was found in a suburban area of the city. Fighters from Daesh are believed to have killed the cleric for refusing to pledge allegiance to the extremist militia.
The prime minister of Libya's internationally recognized government, Abdullah al-Thinni, on Friday accused Islamic State of "perpetrating genocidal crimes" in Sirte, the hometown of late Dictator Muammar Gaddafi.
In an online statement, he called on the United Nations to lift an arms embargo imposed on Libya after the 2011 uprising against Gaddafi.
Daesh established a foothold in Sirte earlier this year and has since expanded in the Mediterranean city, taking advantage of chaos in the oil-rich country.
Libya is divided between an elected government based in the eastern city of Tobruk and an Islamist-backed government in the capital Tripoli.
The unrest has prompted several countries to withdraw their citizens and diplomats from Libya.
