Oil prices fell on expectations that potential additional diesel supplies from Russia would offset supply risks
Oil prices declined on Tuesday, marking the first downward trend in about a week, as markets weighed the supply risks stemming from attacks on Saudi Arabia against the prospect of additional diesel supplies from Russia.
Brent crude futures fell $1.18 (1.1%) to $105.47 per barrel at 06:25 GMT, while WTI crude futures dropped $1.17 (1.3%) to $92.57 per barrel.
Both benchmarks had gained approximately $2 per barrel in the previous session, with Brent closing at its highest level since September 15.
Trump announced that Russia had agreed to supply diesel to global markets and that US sanctions on Russian fuel had been temporarily lifted.
The additional supply from Russia is expected to help ease tightness in global fuel markets and alleviate some of the supply concerns that have recently supported crude oil prices.
However, significant doubts remain regarding a Russia-Ukraine energy truce; reports that Russia struck energy facilities in Ukraine following Trump's announcement have particularly heightened these concerns. 
US lawmakers suggest that a Trump-Putin fuel deal could violate the ban on Russian energy imports.
Concerns regarding the vulnerability of energy infrastructure and maritime shipping routes in the Gulf remained at the forefront following the Houthis' weekend strike on Riyadh's international airport and reports of tanker attacks near the Strait of Hormuz.
While these incidents risk disrupting the recovery in Middle East supplies seen in September, they have also heightened fears of further disruptions along one of the world's most critical energy transit routes.
Although the prospect of new diesel supplies from Russia and more stable shipments from Saudi Arabia has provided some relief, the market remains more concerned about the risk of fresh attacks on Gulf vessels or pipelines than it is reassured by the additional supply.
OPEC+ noted that shipping and insurance costs have surged to unprecedented levels, exceeding one-third of the commodity's value, thereby hindering the efficient transport of crude oil and petroleum products.
OPEC announced that it has lowered its forecast for annual oil demand growth from the 1.4 million barrels per day projected at the start of the year to 400,000 barrels per day.
