Israel targeted Iran’s Defense Ministry headquarters in Tehran and sites it alleged were associated with Iran’s nuclear program, while Iranian missiles evaded Israeli air defenses and slammed into buildings deep inside Israel.

Several buildings in Israel’s Weizmann Institute of Science, one of the country’s top research centers, were damaged in an Iranian strike but there were no casualties, its management told its community members.

The Israeli military has warned that “all of Israel is under fire” after Iran launched retaliatory strikes on Friday, following Israel’s attacks on Iranian military and nuclear targets.
