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 launched a new attack on Israel early on Monday, striking Tel Aviv and the northern port city of Haifa in a fourth day of open warfare. Three people were killed in the country’s centre, while dozens more were injured in the overnight strikes, Israeli media said.
