A terrorist attack occurred in Iran on January 3, 2024, during a commemoration event for General Qasem Soleimani, leading to numerous casualties.

The explosions were activated by remote control near a mosque and are suspected to be the work of either the United States and Israel or the Islamic State, although no group has claimed responsibility.

The international community, including the United Nations and European Union, has condemned the attacks.

Iran has declared a national day of mourning, promised to identify and punish the culprits, and warned of a potential severe response from its supreme leader.

Analysts and Western officials speculate that Sunni militants or separatist groups might be behind the attack, while the US denies any involvement.

The incident underscores Iran's vulnerability and raises concerns about a further escalation in the conflict between Israel and Hamas.
