Israel response to Iran missile attack will 'come fast,' official says
An Israeli official told ABC News on Wednesday that "Israel's response to Iran's attack will be significant and come fast."
Iran launched a large barrage of cruise missiles -- either 220, according to a U.S. official, or 180, according to Israeli Prime Minister Benjamin Netanyahu -- on Tuesday evening.
"This evening, Iran made a big mistake -- and it will pay for it," Netanyahu said shortly after the attack.
