The head of the Israel Defense Forces said Tuesday that “the campaign against Iran is not over” as a ceasefire between the two countries went into effect. President Donald Trump also vowed that Israel will not attack Iran and told Israel to bring its pilots home.

A shaky truce between Israel and Iran, announced after U.S. attacks on Iranian nuclear sites, appeared to be holding.

A fragile ceasefire has paused hostilities between Iran and Israel, but ongoing provocations suggest the risk of renewed war remains high.
