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 death toll is growing as Israel and Iran exchanged missile attacks for a third consecutive day on Sunday, and Israel is warning that worse is to come.

Iranian state television, long controlled by hard-line supporters of the country’s theocracy, repeatedly aired footage of missile strikes on Tel Aviv throughout the morning.
