The nation’s parliament said it was not possible at this time to determine the extent of the attack. “It is impossible to estimate the extent of the damage due to the hostilities that do not stop in the area of the nuclear facility,” the State Nuclear Regulatory Inspectorate said in the post. Russian forces last fired at a nuclear reactor installation in the city two weeks ago, hitting a building where there is equipment that could emit radiation if damaged. The building was set on fire by the bombing, which was later extinguished by firefighters. The research facility is part of the Kharkiv Institute of Physics and Technology, which reportedly produces radioactive materials for medical and industrial use. The Security Service of Ukraine (SBU) has previously warned that possible destruction of the facility would lead to large-scale environmental disaster.

Ukraine has accused Russia of cutting off power to the Chernobyl power plant, the site of the worst nuclear disaster in the world, and called for a temporary ceasefire to allow the power line to be repaired.
