RoydadNaft –  Brent crude futures rose $4.42, or 4.47%, to $97.15 per barrel. U.S. West Texas Intermediate (WTI) crude futures climbed $4.07, or 4.50%, to $94.61 per barrel.

Oil prices jumped more than $4 on Monday as investors grew concerned over Israel’s fresh attacks on Iran and renewed strikes on Lebanon from the previous day.

Brent crude futures rose $4.42, or 4.47%, to $97.15 per barrel (as of 06:09 GMT), while U.S. crude futures increased $4.07, or 4.50%, to $94.61 per barrel.

On Monday, Israel announced it had targeted a petrochemical plant in southwestern Iran and struck military targets in other areas. This came after reports that U.S. President Donald Trump had urged Israeli Prime Minister Benjamin Netanyahu to refrain from further attacks.

This marks the first strike on an energy facility inside Iran since the ceasefire on April 8. Israel said it hit targets at the Mahshahr Petrochemical Complex. A provincial official told the Fars news agency that parts of the plant had been damaged.

Hopes for an imminent end to the wider war and the resumption of crude oil flows through the Strait of Hormuz — which carries about one-fifth of the world’s oil and liquefied natural gas — are now fading.

Monday’s gains offset Friday’s declines, when prices fell amid hopes of easing tensions in the U.S.-Iran conflict. Oil prices have risen about 60% since the war began in late February, but remain below the peak hit in March, when Brent reached $120 per barrel.

On Sunday, Iran fired a barrage of missiles at Israeli targets in response to Israel’s attacks on Lebanon. Nevertheless, Donald Trump insisted that a deal to end the wider war was fully within reach.
