International oil prices have increased once again in the global market.
On Tuesday, Brent crude rose by 26 cents, or 0.3 percent, reaching 83.42 dollars per barrel.
US benchmark West Texas Intermediate (WTI) also climbed by 46 cents, or 0.3 percent, to 81.12 dollars per barrel.
This follows a sharp fall on Monday, when Brent dropped more than 4 percent to around 83.70 dollars after reports of a possible agreement between Washington and Tehran to end their conflict.
However, analysts say many questions remain unanswered about the deal, while uncertainty over the stability of oil shipments through the Strait of Hormuz continues to pressure the market.
