Oil ended lower on Monday, giving back some of last week’s sharp gains amid fading worries of potential retaliation from Russia following weekend airstrikes on the country’s ally Syria.

May West Texas Intermediate crude fell $1.17, or 1.7%, to settle at $66.22 a barrel on the New York Mercantile Exchange. Last week, it rallied by roughly 8.6%. June Brent shed $1.16, or 1.6%, to $71.42 a barel on ICE Futures Europe after rising 8.2% last week.

The U.S. and global benchmark contracts both reached levels last week not seen in more than three years.
