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 confrontation could lead to a broader regional conflict.

Russia has maintained a delicate balancing act in the Middle East for decades, trying to navigate its warm relations with Israel even as it has developed strong economic and military ties with Iran.

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.
