Iran launched dozens of ballistic missiles toward Israel on Friday night in retaliation for Israel's surprise attack early Friday.

Iran says there was damage to its Fordow and Isfahan nuclear sites from an earlier attack as the Israeli PM vows that "more is on the way".

Before Israel launched a wave of strikes against Iran’s nuclear facilities and top military leaders this week, its spies were already on the ground in enemy territory.

The retaliatory strikes came after Israel attacked Iran, killing top military leaders and scientists. The assault destroyed an aboveground nuclear enrichment plant near Natanz, the head of the U.N. nuclear watchdog agency said.

Israeli emergency services have said at least two people were killed in the strikes and dozens of people are injured.

Iran's strikes against Israel will continue, with targets set to expand to include U.S. bases in the region in the coming days, Iran's Fars news agency reported on Saturday, citing senior Iranian military officials.

Israel sent 200 fighter jets to conduct its operation in Iran and has dropped more than 330 different types of munitions so far, Israeli military spokesman Effie Defrin said.

Israeli emergency services have said at least two people were killed in the strikes and dozens of people are injured.
