Trump says we're 'blowing up the whole country' if Iran doesn't make deal in 48 hours

Iran says a projectile has hit near the fence of the Bushehr Nuclear Power Plant, killing a security guard.

An auxiliary building was also damaged but the incident is not believed to have damaged the main parts of the power plant, officials said.

The Atomic Energy Organization of Iran announced the attack on social media. It is the fourth time the facility has been targeted during the war.

The International Atomic Energy Agency were informed by Iran following the strike and and it reported that there was no increase in radiation levels at the plant.

IAEA Director General Rafael Grossi expressed “deep concern" about the reported incident and reiterated a call for "maximum military restraint to avoid risk of a nuclear accident.”
