Israel says it will strike 'every site and every target' of Iran as the conflict escalates.

The two countries continue to exchange air attacks after Iran launched waves of missiles in retaliation for Israeli strikes on Friday.

Israeli Prime Minister Benjamin Netanyahu says Iran plans to threaten everyone.

Middle East correspondent Gregg Carlstrom says this initial strike appeared to be a warning.

"The question is, now, what will Iran do in response? There have been some threats from the Iranian Government throughout the day that they might escalate their own strikes."
