Israel has launched airstrikes on Iran in retaliation for waves of missiles fired at its northern regions on Sunday.
The development marked a day of renewed violence in the Middle East after a fragile ceasefire.
Iranian state television reports that the sound of explosions was heard in Isfahan, Karaj, Tabriz and Tehran.
The strikes occurred after Iran’s Islamic Revolutionary Guard Corps, IRGC, said it had targeted the Ramat David Airbase in northern Israel with ballistic missile fire on the evening of June 7. 
The IRGC claimed that Israel used air-launched ballistic missiles in its attack on Monday morning.
The Israel Defense Forces, IDF, said it identified missiles fired from Iran toward northern Israel and defensive systems are operating to intercept the threat.
“A short while ago, the Israeli Air Force struck military targets belonging to the Iranian terror regime in western and central Iran,” the Israeli military stated.
