Israeli warplanes pounded Iran’s capital overnight and into Wednesday as Iran launched a small barrage of missiles at Israel with no reports of casualties. An Iranian official warned Wednesday that that any U.S. intervention in the conflict would risk “all-out war," Associated Press.

Foreign Ministry spokesman Esmail Baghaei delivered the warning in an interview with Al Jazeera English, saying “any American intervention would be a recipe for an all-out war in the region.” He did not elaborate, but thousands of American troops are based in nearby countries within range of Iran’s weapons. The U.S. has threatened a massive response to any attack.

The latest Israeli strikes hit a facility used to make uranium centrifuges and another that made missile components, the Israeli military said. It said it had intercepted 10 missiles overnight as Iran’s retaliatory barrages diminish, according to Associated Press.
