The State Department raised its travel advisory for Israel to Level 4, the highest level, amid airstrikes from Iran.

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.

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.

The United States advised Americans not to travel to Israel after another wave of Iranian missile attacks struck the country.

The death toll in an earlier strike in Bat Yam, a city adjacent to Tel Aviv, rose as more bodies were extricated from rubble, meanwhile, and a research center at the Weizmann Institute of Science in Rehovot was destroyed in a strike. On Sunday, missiles arrived during the day for the first time.

Missiles and projectiles were seen in the skies over Jerusalem and Tel Aviv early on Sunday as Tehran unleashed a fresh attack on Israel which in turn launched an expanded assault on Iran.

At least seven people were killed and more than 100 injured when an Iranian ballistic missile hit Bat Yam, just south of Tel Aviv, overnight on Sunday, domestic media reported. Other reports put the death toll at six people. Israel's police said residential buildings took a "direct hit that caused extensive damage."

Onlookers gathered on Saturday at a central Tel Aviv residential building next door to Israel’s defense headquarters that was damaged after it took a hit from what appeared to be shrapnel from an overnight missile barrage from Iran.
