Singapore - Oil prices eased in Asia on Monday but analysts said losses were tempered by supply concerns in the crude-rich Middle East after Saudi-led warplanes struck rebel targets in Yemen.
US benchmark West Texas Intermediate for May delivery fell 71 cents to $48.16 and Brent crude for May eased 35 cents to $56.06 in late-morning trade.
"There is a big fear that the deteriorating conflict in Yemen could see a disruptional flow in the supply of oil in the gulf region," Nicholas Teo, market analyst at CMC Markets in Singapore, told AFP.
