US President Donald Trump accused OPEC on Friday of "artificially" boosting oil prices, drawing rebukes from some of the world's top energy exporters.
"Looks like OPEC is at it again. With record amounts of oil all over the place, including the fully loaded ships at sea.
Oil prices are artificially Very High! No good and will not be accepted!" Trump wrote on Twitter.
It was unclear what triggered the tweet, Trump's first mention of OPEC on social media during his term.
US oil prices are near a three-year.
