Mosalla Grand Mosque in Tehran

As Iran prepares for the funeral, a high-ranking general from Iran's Revolutionary Guards was seen publicly for the first time in months.

General Ahmad Vahidi is one of those responsible for Iran's tough stance in its negotiations with the US. Both countries have been locked in months-long discussions to end the war.

The last time he was seen in public was February 8, nearly three weeks before the US-Israeli strikes that marked the beginning of the Iran war.
