Russian military advisers will stay in Venezuela as long as needed, the Russian Foreign Ministry has said, a day after U.S. President Donald Trump called on Moscow to “get out” of the South American country.

Moscow sent military advisers to Venezuela over the weekend amid the escalating political crisis in Venezuela. Trump on Wednesday called on Russia to withdraw from Venezuela and said “all options” were open to make that happen. The Kremlin rejected his call and said its actions there were agreed with the Latin American country’s legitimate government.
