The medical organisation Doctors Without Borders (known by its French acronym, MSF) has said it was ordered to leave Libya by November 9, with no reason given for its expulsion.

MSF had already been forced to suspend its activities in the country in March, and said in a statement on Wednesday that it was told to leave in a recent letter from the Libyan Ministry of Foreign Affairs.

“No reason has been given to justify our expulsion and the process remains unclear,” Steve Purbrick, who heads MSF’s programmes in Libya, said in the statement.

“We believe that MSF still has an important role to play in Libya, particularly in the diagnosis and treatment of tuberculosis, in supporting the Libyan health system, but also in providing access to healthcare for refugees and migrants who are excluded from care and subject to arbitrary detention and serious violence,” he said.
