Operation Outside the Box, also known as Operation Orchard, was an Israeli airstrike on a suspected nuclear reactor, referred to as the Al Kibar site, in the Deir ez-Zor region of Syria, which occurred just after midnight on 6 September 2007. The Israeli and U.S. governments did not announce the secret raids for seven months. The White House and Central Intelligence Agency (CIA) subsequently confirmed that American intelligence had also indicated the site was a nuclear facility with a military purpose, though Syria's Assad government denied this. A 2009 International Atomic Energy Agency (IAEA) investigation reported evidence of uranium and graphite and concluded that the site bore features resembling an undeclared nuclear reactor. IAEA was initially unable to confirm or deny the nature of the site because, according to IAEA, Syria failed to provide necessary cooperation with the IAEA investigation. Syria has disputed these claims. Nearly four years later, in April 2011 during the Syrian Civil War, the IAEA officially confirmed that the site was a nuclear reactor. Israel did not acknowledge the attack until 2018.
