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 in an early morning raid 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.

Israel said Iran had fired over 270 missiles since Friday, 22 of which slipped through the country’s sophisticated multi-tiered air defenses and caused havoc in residential suburbs, killing 14 people and wounding 390 others as of late Sunday.
