BAT YAM, Israel/DUBAI/WASHINGTON — Israel and Iran launched fresh attacks on Sunday, killing and wounding civilians and raising concerns of a broader regional conflict, with both militaries urging civilians on the opposing side to take precautions against further 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."
