Benchmark Brent oil prices jumped above $119 a barrel on Thursday after Iran attacked energy facilities across the Middle East following Israel's strike on its South Pars gas field, a major escalation in the war.
Brent futures were up $7.39, or 6.9%, at $114.77 a barrel by 1026 GMT. Earlier in the session, Brent had climbed more than $10 to a high of $119.13, close to the three-and-a-half-year peak touched on March 9.
US West Texas Intermediate crude was up 27 cents, or 0.3%, at $96.59 a barrel, after earlier gaining almost $4 to trade at $100.02. WTI has been trading at its widest discount to Brent in 11 years.
The US central bank held interest rates steady on Wednesday, projecting higher inflation as policymakers take stock of the impact of the war.
ATTACKS AND COUNTER-ATTACKS
Israel attacked Iran's South Pars gas field, but the US and Qatar were not involved, President Donald Trump said late on Wednesday. South Pars is the Iranian sector of the world's largest natural gas deposit, which Iran shares with US ally Qatar on the other side of the Gulf.
Trump added that Israel would not attack Iranian facilities in South Pars again unless Iran attacked Qatar, and warned that the US would also respond if Iran acted against Doha.
On Wednesday, QatarEnergy had said Iranian missile attacks on Ras Laffan, the site of Qatar's core LNG plants and the world's largest, caused "extensive damage".
European gas prices soared to their highest in more than three years.
Saudi Arabia said it intercepted and destroyed four ballistic missiles launched on Wednesday toward Riyadh and an attempted drone attack on a gas facility.
Saudi Aramco's SAMREF refinery, in the Red Sea port of Yanbu, was also targeted in an aerial attack on Thursday. Oil loadings at the port were disrupted but have now resumed.
Kuwait Petroleum Corporation said an operational unit at its Mina al-Ahmadi refinery was hit by a drone, igniting a limited fire.
