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 has launched retaliatory missile strikes on Israel, killing at least three people and wounding dozens, after a series of blistering Israeli attacks on the heart of Iran’s nuclear program and its armed forces.
