Brent crude prices climbed sharply on Thursday as the US-Iran conflict widened, with both nations signaling an intensification of military operations.

The escalation comes after Houthi rebels in Yemen, allied with Tehran, launched a new offensive targeting Saudi shipping, effectively opening a second front in the region.

The market reaction reflects growing concerns over supply disruption risks in the Red Sea and Gulf of Aden.

Despite the geopolitical deterioration, the US Congress, including Republican lawmakers, voted to disapprove of the war, highlighting a deepening political rift between the legislative branch and the White House.

President Trump, however, ordered a new wave of airstrikes against Iranian military targets, marking the twelfth consecutive night of bombardment.

This development follows President Trump's recent rejection of Iran's latest peace plan offer, which he dismissed as insufficient to end the ongoing conflict involving the United States and Israel.
