KYIV, Ukraine (AP) Russia and Ukraine traded accusations Monday that each side is shelling Europes biggest nuclear power plant in southern Ukraine. Russia claimed that Ukrainian shelling caused a power surge and fire and forced staff to lower output from two reactors, while Ukraine has blamed Russian troops for storing weapons there.

Nuclear experts have warned that more shelling of the Zaporizhzhia nuclear power station, which was captured by Russia early in the war, is fraught with danger.

The Kremlin echoed that Monday, claiming that Kyiv was attacking the plant and urging Western powers to force a stop to that.

Shelling of the territory of the nuclear plant by the Ukrainian armed forces is highly dangerous, Kremlin spokesman Dmitry Peskov told reporters. Its fraught with catastrophic consequences for vast territories, for the entire Europe.

But Ukraines military intelligence spokesman, Andriy Yusov, countered that Russian forces have planted explosives at the plant to head off an expected Ukrainian counteroffensive in the region. Previously, Ukrainian officials have said Russia is launching attacks from the plant and using Ukrainian workers there as human shields.

Yusov called on Russia to make a goodwill gesture and hand over control of the plant to an international commission and the IAEA (International Atomic Energy Agency), if not to the Ukrainian military.

Ukraines ombudsman, Dmytro Lubinets, likewise urged that the United Nations, the IAEA and the international community send a delegation to completely demilitarize the territory and provide security guarantees to plant employees and the city where the plant is based, Enerhodar.

He accused Russia of nuclear terrorism.

The IAEA is the U.N.s nuclear watchdog. Its director-general, Rafael Grossi, told The Associated Press last week that the situation surrounding the Zaporizhzhia plant is completely out of control, and issued an urgent plea to Russia and Ukraine to allow experts to visit the complex to stabilize the situation and avoid a nuclear accident.

U.N. Secretary-General Antonio Guterres voiced support for that idea Monday, saying, any attack to a nuclear plant is a suicidal thing.
