Israel's urgency to attack Iran came after years of covert intelligence operations: Report

Israel had been reportedly surveilling Iran for years before deciding to attack the country’s nuclear operations earlier this month. Its spy agency, Mossad, concluded that Tehran’s nuclear and missile programs had advanced more than previously known.

The attack proved successful, killing several top Iranian military leaders and nuclear scientists and damaging nuclear operations. Israel bombed Iran several other times as the two countries entered into a 12-day conflict that ended with an American-brokered ceasefire after the United States also bombed Iranian nuclear facilities.
