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.

Israel’s Magen David Adom (MDA) emergency service said Monday that four people were pronounced dead after strikes at four sites in central Israel, with 87 injured. The dead were two women and two men, all approximately 70 years old, the MDA said.

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.
