Iranian state TV is reporting "around 500" people have been killed since Israel's 13 June attack on Iran, citing the country's health ministry, BBC reported.
It adds that more than 3,000 people have been injured.
Due to restrictions imposed by Iran's government, BBC journalists are unable to report from inside the country, making it difficult to assess the damage caused by Israel's attacks.
However, one human rights group that is tracking the conflict - Human Rights Activists In Iran - puts the figure for the number of people killed as nearly double.
