Oil futures climbed Friday to post gains for the week, holding ground at their highest since early 2014. Prices got a boost on the potential for a U.S.-led military strike on Syria and a report from the International Energy Agency that said global oil supplies are falling back toward their five-year average. May West Texas Intermediate crude rose 32 cents, or 0.5%, to settle at $67.39 a barrel on the New York Mercantile Exchange, holding ground at its highest since Dec. 3, 2014. For the week, the U.S. benchmark gained roughly 8.6%.
