Washington, Mar 27 (AP) A federal appeals court in the US on Wednesday refused to lift an order barring the Donald Trump administration from deporting Venezuelan migrants to El Salvador under an 18th century wartime law.

A split three-judge panel of the US Court of Appeals for the district of Columbia Circuit upheld a March 15 order temporarily prohibiting deportations under the Alien Enemies Act of 1798.

The Justice Department appealed after US district judge James Boasberg blocked more deportations and ordered planeloads of Venezuelan immigrants to return to the US.
