Oil prices extended losses on Tuesday after reports of OPEC+ plans to proceed with output increase in April while further price pressure was applied by U.S. tariffs on Canada, Mexico and China as well as Beijing's retaliatory tariffs. Brent futures were down $1.04, or 1.45%, at $70.58 a barrel by 1417 GMT while U.S. West Texas Intermediate (WTI) crude was off 73 cents, or 1.07%, at $67.64. "The current downward trend in oil prices is primarily driven by OPEC+'s decision to increase output and the introduction of U.S. tariffs," said Darren Lim, commodities strategist at Phillip Nova.
