Seven Israeli soldiers were killed Tuesday in the southern Gaza city of Khan Younis when their armored vehicle was struck by an explosive, an Israeli military official said Wednesday.

After twelve days of intense strikes between Israel and Iran – punctuated by the United States’ bombing of Iranian nuclear sites over the weekend and Tehran’s performative retaliation – a US-brokered ceasefire appeared to be holding on Tuesday.

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.
