Israeli fighter jets destroyed several aboveground buildings at Natanz, Iran's main uranium enrichment facility, images show.

The stakes could not be higher as Iranian officials have called the attack “ a declaration of war ” and vowed that destroyed nuclear facilities “would be rebuilt.” Israel, meanwhile has warned its campaign will continue “ for as many days as it takes .”

Iran and Israel exchanged more deadly missile strikes overnight Friday after Israel mainly attacked Iranian nuclear and military targets one day earlier.
