An airstrike near the Bushehr nuclear power plant has killed a plant security officer and damaged a building on the site in The Gulf, Iran's official IRNA news agency reported on Saturday.

IRNA reported that the projectile had struck near a fence around the site and that there had been no damage to the main parts of the power plant. The International Atomic Energy Agency (IAEA) said the Iranian authorities had informed it of the attack.

There have now been four attacks near the power plant since the war started on February 28, according to Iranian reports.

The plant, Iran's sole nuclear power plant, lies around 760 kilometres south of Tehran. Russia's Rosatom is currently building a second block at the facility, which has been in operation since 2011.

Separately, Iran's semi-official Tasnim news agency reported airstrikes on the Mahshahr Special Petrochemical Zone at the head of The Gulf. It reported three strikes and large explosions, citing the governor's office.

The companies Fajr 1 and 2, Rijal and Amirkabir had been hit, the agency, which is linked to the Islamic Revolutionary Guard Corps (IRGC), said, adding that deaths and injuries were likely.

The Israeli military declined to comment on the report.

Tasnim reported that a complete evacuation of all active industrial units in the region had been ordered.

The Israeli military reported attacks on Friday on Iranian leadership facilities in Tehran that targeted air defences and arms production.

Israeli media reported Iranian missile attacks overnight on an industrial zone in the Negev Desert in the south of Israel that caused a fire.

Other reports referred to power outages in Greater Tel Aviv after an Iranian attack hit a power line. Israel's Magen David Adom rescue service reported one man injured.
