The first direct war between Israel and Iran halted on Tuesday after President Donald Trump brokered a ceasefire between the two nations, just two days after the United States launched strikes against Iranian nuclear facilities.

If the fragile ceasefire holds, it will mark the end of what Trump is calling the “12 Day War.” The war was marked by Israeli air, drone, and missile strikes against Iran, and Iran fought back with ballistic missile and drone strikes against Israel. The war resulted in 29 Israelis killed and thousands wounded, compared to at least 600 Iranians killed and several thousand wounded.
