Israel’s military chief has said that the country’s ongoing campaign of strikes on Iran was on a “completely different scale” to a previous 12-day war fought between the foes in June last year.

“We are embarking on an operation that is taking place at a completely different scale — more complex and more complicated,” Lieutenant General Eyal Zamir was quoted as saying in a military statement.

“I know that the preparation was short but intensive and incredibly thorough,” he added.
