Israel's strikes on Iran's nuclear installations so far pose only limited risks of contamination, experts say. But they warn that any attack on the country's nuclear power station at Bushehr could cause a nuclear disaster.

Over the past week, Israel has pummeled Iran with airstrikes and Iran has sent barrages of ballistic missiles and drones toward Israel. At least 24 people in Israel and 224 people in Iran have been killed in attacks since June 13, their governments have reported.
