Israeli Prime Minister Benjamin Netanyahu said Monday that Israeli strikes against Iran have set Iran’s nuclear program back a “very, very long time.”

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."

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.
