A rare daytime missile barrage on Tel Aviv forces millions into shelters as Israeli forces retaliate against Iran's missile-launching capabilities.

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."

There is no sign the conflict is ending soon and many in the region fear a wider war as they watch waves of attacks.

Both countries have closed their airspaces, leaving few options for citizens of other countries seeking to leave.

Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.

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

Video verified by CNN captures the dramatic moment a missile struck in vicinity of the Kirya, an area of Tel Aviv that’s home to an urban military base housing Israel’s Defense Forces.

Iran and Israel targeted each other with airstrikes early on Saturday after Israel launched its biggest-ever offensive against its longtime foe in a bid to prevent it from developing a nuclear weapon.
