Oil prices held steady on Friday near 2015-highs reached the session before, remaining on track for weekly gains after renewed air strikes in Yemen stoked concerns on the security of Middle East oil shipments. Crude prices on both sides of the Atlantic have surged almost $10 a barrel this month amid rising tension in the Middle East, while slowing U.S. production growth and signs of stronger global demand have also provided support. Brent crude for June delivery had climbed 22 cents to $65.09 a barrel by 0706 GMT (3.06 a.m. ET), after settling up $2.12 on Thursday.
