A team from the United Nations nuclear watchdog on Monday headed to Ukraine's Zaporizhzhia nuclear plant, the agency's chief said, as Russia and Ukraine traded accusations of shelling in its vicinity, fuelling fears of a radiation disaster.
International Atomic Energy Agency (IAEA) chief Rafael Grossi has for months sought access to the Zaporizhzhia plant, Europe’s biggest, which has been occupied by Russian forces and run by Ukrainian workers since the early days of the six-month-old war.
His announcement came hours after Russia and Ukraine traded claims of rocket and artillery strikes at or near the plant on Sunday, intensifying fears that the fighting could cause a massive radiation leak. Under the barrage of shelling last week, the facility was already temporarily knocked offline.
“The day has come,” Grossi wrote on Twitter, adding that the Vienna-based IAEA’s “Support and Assistance Mission ... is now on its way.”
“We must protect the safety and security of #Ukraine’s and Europe’s biggest nuclear facility,” he wrote. “Proud to lead this mission which will be in #ZNPP later this week.” Grossi, who did not provide a more precise timeline or give further details, posted a picture of himself with 13 other experts.
The IAEA tweeted separately that the mission would assess physical damage, evaluate the conditions in which staff are working at the plant and "determine functionality of safety & security systems." It would also "perform urgent safeguards activities," a reference to keeping track of nuclear material.
The IAEA's mission to the nuclear plant in Ukraine will be the agency's hardest to date, Ukraine Foreign Minister Dmytro Kuleba warned Monday.
"This mission will be the hardest in the history of the IAEA, given the active combat activities undertaken by the Russian federation on the ground and also the very blatant way that Russia is trying to legitimise its presence," Kuleba said during a visit to Stockholm.
Mikhail Ulyanov, Russia's permanent representative to the international organisations in Vienna, said Monday that Moscow welcomes the IAEA upcoming mission to the Zaporizhzhia plant, the RIA Novosti news agency reported. He also added Russia had made a significant contribution to the visit.
The U.N. and Ukraine have called for a withdrawal of military equipment and personnel from the nuclear complex, Europe's largest, to ensure it is not a target.
The two sides have for days exchanged accusations of courting disaster with their attacks.
With fears mounting of a nuclear accident in a country still haunted by the 1986 Chornobyl disaster, Zaporizhzhia authorities are handing out iodine tablets and teaching residents how to use them in case of a radiation leak.
Russian forces fired at Enerhodar, the city where the plant is located, the chief of staff of Ukraine's President Volodymyr Zelenskyy, said late on Sunday on his Telegram channel alongside a video of firefighters dousing burning cars.
"They provoke and try to blackmail the world," Andriy Yermak said.
Ukraine's military earlier reported shelling of nine more towns on the opposite side of the Dnipro River.
Russia's Defense Ministry reported more Ukrainian shelling at the plant over the weekend. Nine shells fired by the Ukrainian artillery landed in the plant's grounds, Russian Defense Ministry spokesperson Igor Konashenkov said.
"At present, full-time technical personnel are monitoring the technical condition of the nuclear plant and ensuring its operation. The radiation situation in the area of the nuclear power plant remains normal," he said in a statement.
The Russian state news agency cited authorities as saying they had downed a Ukrainian drone that planned to attack the nuclear-waste storage facility at the plant.
Two of the plant's reactors were cut off from the electrical grid last week due to shelling.
Ukrainian state nuclear company Energoatom said it had no new information about attacks on the plant and Reuters could not verify the accounts.
The U.S. State Department said on Sunday that Russia did not want to acknowledge the grave radiological risk at the plant and had blocked a draft agreement on nuclear non-proliferation because it mentioned such risk.
In the Donetsk region of eastern Ukraine, Russian forces shelled military and civilian infrastructure near Bakhmut, Shumy, Yakovlivka, Zaytsevo, and Kodema, Ukraine's military said early on Monday.
Russian strikes killed eight civilians in Donetsk province on Sunday, its governor Pavlo Kyrylenko said.
Russia denies targeting civilians.
Zelenskyy, in a video address late on Sunday, vowed "the occupiers will feel their consequences – in the further actions of our defenders."
"No terrorist will be left without an answer for attacks on our cities. Zaporizhzhia, Orykhiv, Kharkiv, Donbass – they will receive an answer for all of them," he added.
Russia invaded Ukraine on Feb. 24 in what it called a "special military operation" to demilitarize its southern neighbor. Ukraine, which won independence when the Russian-dominated Soviet Union broke up in 1991, and its Western allies have dismissed this as a baseless pretext for a war of conquest.
The invasion of Ukraine has touched off Europe's most devastating conflict since World War II.
Thousands of people have been killed, millions displaced and cities blasted to ruins. The war has also threatened the global economy with an energy and food supply crisis.
The regional governor has said Russian shelling has displaced more civilians in the east, where three-quarters of the population has fled front-line Donetsk province, which comprises part of the wider Donbass region.
The United States and its allies have imposed sweeping sanctions on Russia for its invasion and sent billions of dollars in security assistance to the Ukrainian government.
Russia has said sanctions will never make it change its position and Western arms supplies only drag out the conflict.
Kuleba will travel to Sweden and the Czech Republic this week and push for more sanctions on Russia, including a European Union-wide visa ban for Russians.
European Union foreign ministers meeting this week are unlikely to unanimously back a visa ban on all Russians, the EU's foreign policy chief told Austria's ORF TV.
