Israeli forces stepped up bombing of Iranian cities, while Iran pierced Israeli air defences with a successful volleys of retaliatory missile strikes.

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."

Tel Aviv stocks erased early losses and ended higher on Sunday in the first trading session since the start of a wave of missile strikes between Israel and Iran on Friday, as Israel and its economy attempt to remain as open as possible.

Eliezer Reinhold lives in a suburb of Tel Aviv, Petah Tikva. Reinhold is the father-in-law of Florida State University’s Chabad of Tallahassee Rabbi, Schneur Oirechman. Reinhold visits Tallahassee several times a year, but is currently in Israel. He said the last few days have been long, and every night brings the chance for missile attacks.

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.

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