The leaders of France, Germany and Italy on Saturday threatened for the first time to use sanctions against countries that continued to violate a United Nations arms embargo on Libya. French President Emmanuel Macron, German Chancellor Angela Merkel and Italian Prime Minister Giuseppe Conte urged "all foreign actors to end their increasing interference and to fully respect the arms embargo established by the United Nations Security Council" in a joint statement issued by the French presidency after meeting in Brussels. Turkey has intervened decisively in recent weeks in Libya, providing air support, weapons and allied fighters from Syria to help the internationally recognised government based in Tripoli repel a year-long assault by the forces of eastern commander Khalifa Haftar. Haftar is backed by the UAE, Egypt and Russia, which have also been accused by the UN of breaking the embargo.
