Oil prices surged in early Asian trade on Thursday after the US reportedly attacked Iran for the second time this week, raising doubts over a peace deal.
Brent crude futures for July rose 1.9% to $96.03 a barrel, while WTI crude futures gained 1.9% to $90.36 a barrel.
Three explosions were heard in Bandar Abbas, Iran. The US military carried out new strikes on an Iranian military site, Reuters reported.
The attacks were the second such strike by the US this week. They were again described as 'self-defense,' with a ceasefire reportedly still in place.
President Donald Trump dismissed reports that Iran would reopen the Strait of Hormuz within 30 days. He also rejected joint control of the strait by Iran and Oman.
Crude prices had fallen sharply on Wednesday amid expectations of a peace deal. But Trump's comments indicated a deal was not as close as markets had hoped.
Brent crude had broken below $100 a barrel on hopes of Hormuz reopening. However, shipping through the strait remains well below pre-war levels.
The closure continues to disrupt about a fifth of global oil supplies, though a steady trickle of ships is passing through.
