At least 24 people have been killed in Israel as Iran launched retaliatory airstrikes targeting civilian areas. A U.S. Embassy branch in Tel Aviv suffered minor damage.

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.

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