Oil prices rose on Friday after the United States and Iran intensified attacks across the Gulf, disrupting oil flows through the Strait of Hormuz and raising fears of further supply disruptions in the Red Sea.
Brent crude futures rose 70 cents, or 0.83 percent, to $84.93 a barrel by 0312 GMT, while US West Texas Intermediate (WTI) crude gained 81 cents, or 1.03 percent, to $79.76 a barrel, recovering losses from the previous session.
Both benchmarks have gained about 12 percent this week. Brent is on course for a third consecutive weekly gain, while WTI is set for a second.
The latest gains came after the United States launched two waves of air strikes against targets near Iran's southern coast on Wednesday and continued attacks on Thursday, marking the sixth consecutive night of attacks, according to US Central Command.
Meanwhile, Qatar's Defence Ministry said its armed forces intercepted an Iranian missile attack early on Friday. The Interior Ministry said a child was injured by shrapnel from the interception.
International Energy Agency Executive Director Fatih Birol warned that energy security remained a major concern.
"We should be worried, and I am worried, if the situation does not improve in the next few weeks," he said at a Council on Foreign Relations event in Washington on Thursday.
Adding to supply concerns, three sources told Reuters that Iran had instructed its Houthi allies to prepare to close the Red Sea shipping route if US strikes target the country's power infrastructure.
