Israel said it has launched a series of strikes against Iran that included dozens of military targets, including the country's nuclear program, according to the Israel Defense Forces.

The IDF said the operation, titled "Rising Lion," comes after intelligence identified that Iran has "significantly advanced towards obtaining a nuclear weapon," alleging this capability would allow them to act against Israel.

Israel estimates Iran now has enough enriched material for several nuclear bombs, the IDF and an Israeli official familiar with the operation told ABC News.

Defense Minister Israel Katz described the strikes as "preemptive" and declared a state of emergency.

"Following the State of Israel's preemptive strike against Iran, a missile and drone attack against the State of Israel and its civilian population is expected in the immediate future," Katz said in a statement.

Air raid sirens sounded in Tel Aviv following the announcement.
