A loud explosion was heard in Shiraz in Iran, prompting local reports of a blast in the area earlier today.
Initial reactions on social media sparked alarm, but provincial officials have suggested the sound may have come from nearby fireworks or a small explosive device, not a major incident, and authorities are investigating the cause.
At this stage there is no verified confirmation of a large scale explosion, attack, or significant damage, and emergency services have not issued further details.
The situation remains unclear as inquiries continue.
