Oil prices fell on Friday morning in Asia as investors express doubts about a U.S.-mediated truce between Russia and Saudi Arabia.

U.S. Crude Oil WTI Futures jumped almost 25% in the last session as U.S. President Donald Trump tweeted that Saudi Arabia and Russia had agreed to a cut of “approximately 10 million barrels, and maybe substantially more.”

He added, “If it happens, will be GREAT for the oil & gas industry!”

Saudi Arabia also called for an “urgent” meeting between OPEC and its allies via the Saudi Press Agency yesterday.

But the black liquid could not hold onto its gains as International Brent Oil Futures dropped 1.55% to $29.17 by 9:57 PM ET (2:57 AM GMT) and U.S. Crude Oil WTI Futures slid 4.42% to $24.2
