Oil prices rise 4% at the Asian markets opening
Oil prices rose 4% at the start of trading in Asian markets on Monday, before limiting gains due to concerns over supply disruptions from the conflict between Iran and Israel.

The prices rose after U.S. attacks over the weekend targeted Iranian nuclear facilities, and threats of retaliation from Tehran fueled concerns.
Earlier in the day, U.S. WTI crude rose 2.53% to $75.71 per barrel, after surpassing $77, while North Sea Brent crude rose 2.42% to $78.87 per barrel, after exceeding $81, reaching its highest level in six months.
Israel has been conducting an offensive against Iran since June 13, citing progress in Iran’s nuclear program and the missile production threat Tehran poses to the country.
Iran repeatedly denies developing nuclear weapons and claims the right to conduct peaceful nuclear activities.
Tel Aviv’s attacks destroyed Iran’s nuclear infrastructure and killed senior military commanders and scientists involved in the nuclear program.
Tehran has responded with missile waves targeting major Israeli cities and various military facilities across the country.
Late Saturday into Sunday, the United States became militarily involved in the conflict, employing B-2 bombers, which, according to the Pentagon (Department of Defense), managed to “eliminate” Iran’s nuclear ambitions.
The attacks “will have eternal consequences,” assured Iran’s Foreign Minister, Abbas Araghchi, stating that Tehran keeps “all options open to defend its sovereignty, interests, and people.”
