Oil prices at highest levels in 4 years

(VOVWORLD) - Oil prices rose to 81 USD a barrel at the close of trading Monday, the highest level since 2014, after the Organization of Petroleum Exporting Countries (OPEC) said it will not raise its output.

At a meeting Sunday in Algeria, OPEC rejected US President Donald Trump's call to open the taps, with both Saudi Arabia and Russia saying they won't produce significantly more oil.
