WASHINGTON (Reuters) - The United States on Saturday welcomed a 48-hour cease-fire in southern Syria and called on the Syrian government to honor its commitments during that period.

“We will judge this initiative by the results, not the words,” State Department spokeswoman Heather Nauert said in a statement. “The opposition should similarly halt attacks to allow the ceasefire to endure - and hopefully be extended - and humanitarian aid to reach those in need.”
