At least 224 people have been killed in Iran by Israeli strikes, Netanyahu's office said on Monday. The Israel Defense Forces issued a warning to residents in District 3 of Tehran to "immediately leave" ahead of planned strikes there.

Israel launched blistering attacks on the heart of Iran's nuclear and military structure Friday, deploying warplanes and drones previously smuggled into the country to attack key facilities and kill top generals and scientists -- a barrage it said was necessary before its adversary got any closer to building an atomic weapon.
