Nineteen Israelis have been reported killed in Iranian attacks since Friday, while Iran’s health ministry says 224 have died in Israeli strikes.

Dozens of others were injured overnight across Israel, the authorities said. Israel was striking military sites in Iran and the four-day-old conflict showed no sign of slowing.

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