U.S. inflation remained surprisingly muted through May, with limited impact from President Donald Trump’s tariffs. But U.S. airstrikes on Iran’s nuclear facilities over the weekend could contribute to pressures that may send price gains back to the highest levels in two years.

Few people inside the administration knew the president was moving forward with plans for the attack, even late last week.

Iran said Monday that the number of missiles fired matched the number of bombs dropped by the U.S. over the weekend.

Israel says it has hit access routes to Iran's main nuclear enrichment site a day after US attacks. The UN's nuclear watchdog says it must be allowed to assess the damage to Iran's nuclear programme.

Trump said the U.S. hit the Fordow, Natanz and Isfahan nuclear sites. Iran’s foreign minister called it a “dangerous military operation” against his country.
