Crude oil futures rose more than 3% on Sunday after Israel attacked two natural gas facilities in Iran, amid concerns that the fighting could spread to energy infrastructure and disrupt supplies in the region.
U.S. crude oil rose $2,72, or 3,7 percent, to $75,67 a barrel. Global benchmark Brent crude rose $3,67, or 4,94 percent, to $77,90 a barrel.
Israeli drones struck the South Pars gas field in southern Iran on Saturday, Iranian state media reported. The strikes hit two natural gas processing plants, state media said. Iranian missiles also hit a major oil refinery in Haifa, according to The Times of Israel.
Oil prices closed up more than 7 percent on Friday after Israel launched airstrikes on Iran's nuclear and ballistic missile programs and top military leaders. That brings U.S. crude oil to a total of 13 percent last week.
Iran is considering closing the Strait of Hormuz, a top Iranian commander said Saturday. Energy analysts say about a fifth of the world's oil passes through the strait to reach global markets, and closing it could send oil prices above $100 a barrel.
Analysts pointed to the presence of the US 5th Fleet in Bahrain and said they did not believe Iran could close the strait for this reason; however, they pointed out that there could be attacks on tankers passing through the region and also warned that the strait could be mined.
