The Israeli military issued two warnings about incoming missiles early Wednesday morning, local time, saying that launches had been detected aimed from Iran and that it was trying to intercept them. The two warnings were separated by less than an hour.

Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

Since Israel’s surprise attack against Iran, Iran has retaliated with hundreds of missiles and drones launched against major cities across Israel.
