DUBAI, United Arab Emirates (AP) — Iran and Russia both allege a projectile struck the grounds of the Bushehr nuclear power plant in the Islamic Republic, raising the specter of a radiological incident as Tehran’s war with Israel and the United States rages.

Neither Iran nor Russia say there was any release of nuclear material in the incident Tuesday, but it again underlines a longtime worry of Iran’s neighbors — that the power plant on the shores of the Persian Gulf could be stricken by either an attack or an earthquake.

Here’s what to know about the incident, the plant itself and Iran’s wider nuclear program, which remains a reason U.S. President Donald Trump points to for starting the war alongside Israel against Iran on Feb. 28.

Reports of a projectile striking there

Russia’s state-run Tass news agency quoted Rosatom CEO Alexey Likhachev late Tuesday as claiming “a strike hit the area adjacent to the metrology service building located at the Bushehr Nuclear Power Plant site, in close proximity to the operating power unit.” Russian technicians from Rosatom operate the plant, using Russian-made, low-enriched uranium.
