What happened (Israel Katz’s allegations)

Israel’s Defence Minister Israel Katz alleged that American warplanes used Israeli bases during attacks on Iran.

Israel Katz reiterated that Israel is prepared to retaliate with full force if Israel comes under fire.

Israel Katz argued that Iran was firing at regional forces rather than at Israel, and Israel Katz used this claim to suggest that the aircraft were operating from Israeli territory.
