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.

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

A volley of missiles launched by Iran killed eight people and injured nearly 100 in Israel on Monday as the conflict between the two countries entered its fourth day.

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.

Delta Air Lines Inc. and United Airlines Holdings Inc. suspended flights to Tel Aviv following Israel’s bombing of Iran and the closure of Israel’s airspace.

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