Sources report the strike as the trigger for widespread fighting and noted that Iran was expected to appoint a new supreme leader amid the chaos.

The appointment marks an unprecedented intra-family transfer of power since the 1979 revolution and came as Iranian authorities faced intense military pressure and domestic unrest.

Iran succession controversy

The selection process has been portrayed as controversial and contested, with reports saying the Assembly made a swift choice under pressure from Iran’s Islamic Revolutionary Guard Corps (IRGC).

Critics argue the transfer of power to Mojtaba Khamenei signals a move toward dynastic rule.

Observers note Mojtaba holds no formal public office but is a long-time, low-profile gatekeeper with deep IRGC ties.

The Assembly of Experts, tasked by constitution to elect a supreme leader, saw its offices hit during the crisis as members rushed to choose a successor.

Domestic protests and unrest

Reports indicate street demonstrations with chants such as "Death to Mojtaba."

Analysts and pro-democracy movements have long suspected Mojtaba of involvement in past repression.

The strikes and ensuing crisis occurred against a backdrop of existing anti-government unrest and heavy civilian casualties from the campaign of strikes.
