Gold rose more than 1% on Monday to more than $5,350 an ounce, hitting a one-month high as demand for safe-haven assets strengthened after a joint U.S.-Israel attack on Iran that killed Iranian Supreme Leader Ayatollah Khamenei over the weekend.

The conflict has severely disrupted maritime traffic in the oil-rich Gulf region.

Iran has also launched attacks on U.S. assets in neighboring countries, including the United Arab Emirates, Bahrain, Kuwait, Qatar, Saudi Arabia, Jordan, Iraq, and Syria.
