The Israeli Defense Forces claimed on Tuesday that they carried out a large-scale attack on an underwater research center in the Iranian city of Isfahan. According to the Israeli statement, the facility is the country’s only site involved in submarine production and naval support operations. Iran has not yet issued any comment regarding the reported strike.

Earlier, BBC Verify reported that an airstrike in Isfahan had damaged a multistory building and nearby shops, though it remained unclear whether that incident was linked to the same attack mentioned by Israel. The report did not confirm the extent of the damage or any casualties.

The situation adds to regional tensions, but no immediate response or confirmation from Iranian authorities was available at the time of reporting.
