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

Israel struck Iran's state-run television station during a live broadcast, forcing a reporter to run off camera following an explosion.

A fresh wave of Iranian missiles were launched at northern Israel, Israel Defense Forces said in a statement. Israel's emergency services said there are no reports of any casualties, aside from some isolated incidents of injuries as people raced to bomb shelters.
