TEHRAN – Iran’s anti-aircraft forces shot down a drone in central Tehran on Monday as it approached the offices of the president and the supreme leader.

Residents in central Tehran heard loud gunfire and an explosion, according to reports on social media.

Local media outlets reported that the drone was shot down as “it approached the no-fly zone” near the office of the supreme leader.

Last month, an unmanned aircraft that later appeared to have been operated by a film crew shooting aerial footage for a documentary was shot down by anti-aircraft guns.

The drone, which belonged to a documentary-making team that had permission to film, unintentionally started moving it towards the no-fly zone.

Pasteur Street in central Tehran is highly secured as key government institutions are located there.
