TEL AVIV, Israel (AP) — Iran fired a new wave of missile attacks on Israel early Monday, killing at least five people, while Israel claimed in the fourth day of the conflict that it had now achieved “aerial superiority” over Tehran and could fly over the Iranian capital without facing major threats.

At least 24 people have been killed in Israel as Iran launched retaliatory airstrikes targeting civilian areas. A U.S. Embassy branch in Tel Aviv suffered minor damage.

The Israel Defense Forces said alerts were activated in several areas of the country after the detection of missiles launched from Iran toward Israel. The Air Force was working to intercept them, the IDF said.

Iran announced it had launched some 100 missiles and vowed further retaliation for sweeping attacks on its military and nuclear infrastructure.

Dozens of others were injured overnight across Israel, the authorities said. Israel was striking military sites in Iran and the four-day-old conflict showed no sign of slowing.

The conflict between Israel and Iran has forced many countries in the Middle East to close their airspace, as Israeli jets and Iranian exploding drones and missiles fly over their night skies.

Israeli citizens were ordered to head to bomb shelters on Friday night amid retaliatory missile strikes from Iran.
