People in Iran have been describing their experiences as Israel and the US continue to bomb targets across the country.
The attacks began on Saturday morning with the killing of Iran's Supreme Leader Ayatollah Ali Khamenei, shocking supporters and opponents. Since then, military and strategic sites have been attacked day and night.
The authorities have blocked the internet, making it very difficult for people to communicate with the outside world.
Despite the restrictions, the BBC has managed to speak some individuals. Their names have been changed to protect their identities.
Hossein, in the city of Karaj, west of the capital Tehran, said there was a big blast near his home on Monday.
