Analysis Summary:

The article's accuracy is mixed. The claim of Israel striking bases and nuclear sites across Iran is not directly supported by the provided sources, although the killing of Iranian officials is mentioned. The claim of wiping out Iran's top military chain of command is partially supported by sources discussing similar actions against Hezbollah, but not directly against Iran itself. The article exhibits moderate bias through its framing of the event and potentially sensationalized language.

Detailed Analysis:

• Claim 1:** "Israel struck bases and nuclear sites across Iran multiple times overnight..."
