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.

It remains to be seen how long the truce will hold and whether it will pave the way for a nuclear deal between the U.S. and Iran.

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