Early Friday morning, local time, Israel launched dozens of strikes against Iran and declared a state of emergency, according to Defense Minister Israel Katz.

“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.

The U.S. did not provide any assistance or have any involvement in the Israeli strike, a U.S. official told ABC News.

Israel Defense Forces spokesperson Brigadier General Effie Defrin says that “Iran launched approximately 100 UAVs towards Israeli territory, which we are working to intercept.”

Israel says it is planning to use its air defenses to intercept the drones.

The state of emergency means nobody is allowed to be out on the streets and almost all businesses, including schools, offices and supermarkets, have also been shut as the airspace over Israel is closed.
