Iran launched missiles at Israel. Israeli defense systems are active, and leaders warn of an escalating conflict.

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 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.

Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program, killing several nuclear scientists as well as high-ranking military leaders, according to Israeli officials.
