By Alexander Cornwell, Parisa Hafezi and Jeff Mason TEL AVIV/DUBAI/WASHINGTON (Reuters) -Iranian missiles struck Israel's Tel Aviv and the port city of Haifa before dawn on Monday, destroying homes and fuelling concerns among world leaders at this week's G7 meeting that the battle between the two old enemies could lead to a broader regional conflict.

The U.S. did not provide any military assistance or have any involvement in the Israeli strike, a U.S. official told ABC News. People in Israel can leave shelters, but should stay near them in "all regions of the country," the Israel Defense Forces said in a post on X.
