NEW YORK (Reuters) -Dual risks kept investors on edge ahead of markets reopening late on Sunday, from heightened prospects of a broad Middle East war to U.S.-wide protests against U.S. President Donald Trump that threatened more domestic chaos.

U.S. President Donald Trump said on Saturday "this war in Israel-Iran should end," with his comments coming in a social media post on his call with Russian President Vladimir Putin.

Trump had repeatedly pushed Israeli Prime Minister Benjamin Netanyahu to delay an Israeli attack to give diplomacy more time.
