An Iranian military factory in Isfahan, Iran was hit by a drone attack on Tuesday, according to Iranian officials.

The attack occurred at a military plant in the central city of Isfahan, located in the central province of Isfahan. A loud blast was heard at the plant, according to witnesses.

Iranian officials said the attack was “unsuccessful” and did not cause any casualties or damage. However, the blast was strong enough to be heard in the city.

The attack comes amid heightened tensions between Iran and the United States, which have been at odds since the US withdrew from the 2015 nuclear deal in 2018.

The incident was caught on video and shared on social media, with many people reporting hearing the loud explosion.

The Iranian government has yet to comment on the incident, but has previously accused the US of using drones to carry out attacks in the region.

The US has denied any involvement in the attack and has not commented further.

The attack is the latest in a series of incidents between Iran and the US, and has raised fears of further escalation in the region.
