WASHINGTON (Reuters) – U.S. Secretary of State Mike Pompeo voiced grave concern about ongoing hostilities in the northerly Tigray region of Ethiopia during a telephone call with Ethiopian Prime Minister Abiy Ahmed, the U.S. State Department said in a statement on Monday.

“Secretary Pompeo took note of the Government of Ethiopia’s Nov. 28 announcement of the end of major military operations, but reiterated the United States’ grave concern regarding ongoing hostilities and the risks the conflict poses,” State Department spokesman Cale Brown said, saying that Pompeo called for a “complete end” to the fighting and constructive dialogue.
