Oil prices edged lower on tuesday:ran talks. Brent crude fell 20 cents, or 0.3%, to $77.70 a barrel, while US West Texas Intermediate declined to $73.74 a barrel, down 12 cents, or 0.2%.

According to Qatar News Agency, prices fell more than 3% on Monday after the US granted Iran a 60-day sanctions waiver following initial talks. This waiver has added to the uncertainty in the oil markets, as traders and investors assess the potential impact on global crude supply and the geopolitical landscape in the region.
