The Grand National Assembly of Turkey passed a bill on Thursday authorizing the government to deploy troops into Libya.

The Turkish Parliament held a special session this week to decide whether to authorize President Recep Tayyip Erdoğan to deploy military forces into Libya to support the Government of National Accord (GNA), the United Nations-recognized government of Libya. The GNA has been fending off increasing attacks by military forces under the command of General Khalifa Hifter, who controls the eastern part of the country. The final vote was 325 in favor to 185 against, according to a statement made by Parliament Speaker Mustafa Sentop, with nearly all of the members of opposition parties voting against the proposal. The bill gives Erdoğan the discretion to determine how and when to deploy the Turkish military for a period of one year.

US President Donald Trump cautioned Erdoğan from deploying troops to Libya on a phone call Thursday afternoon. According to a transcript of the call obtained by Politico, Trump said that foreign interference had “complicated the situation” in the country. The GNA is officially recognized by the United Nations and supported by Turkey, Qatar and Italy, while Hifter’s forces have received aid from Russia, France and the United Arab Emirates.
