Oil prices fell amid expectations of an increase in "OPEC+" production in its upcoming meeting.

Oil prices witnessed a slight decline during Tuesday's trading, amid expectations that the "OPEC+" alliance will increase crude supplies during its meeting scheduled for this week.

Data showed a decrease in Brent crude futures by 12 cents (0.19%), settling at $64.62 per barrel, while WTI crude futures dropped by 19 cents (0.31%), recording $61.34 per barrel.

In this regard, Daniel Hynes, an analyst at "ANZ Bank," commented: "Crude oil prices experienced a slight decline as the market anticipates OPEC's production increase forecasts."

Reuters revealed that three sources within the "OPEC+" alliance indicated that eight countries from the alliance _ which had previously committed to voluntary production cuts _ will meet on May 31, one day before the official alliance meeting.

The meeting is expected to determine the production policy for July, with previous sources suggesting a possible increase in production by about 411,000 barrels per day.

This comes after "OPEC+" agreed earlier this month to accelerate the pace of production increases for the second consecutive month in June.
