Iran has launched retaliatory missile strikes on Israel into Saturday morning after a series of blistering Israeli attacks on the heart of Iran’s nuclear program and its armed forces, killing at least three people and wounding dozens.

The sweeping attacks by Israel, which began early Friday, have killed more than 70 people, including four of Iran’s top security chiefs, and damaged Iran’s main nuclear site at Natanz. Iran retaliated by launching scores of missiles at Israel. At least three people have been killed and dozens more wounded during these attacks.
