Chernobyl Drone Attacks Gamble With Safety of Millions, UNDP Warns

Chernobyl drone attacks are ‘really gambling with the safety of millions of people’, United Nations Development Programme (UNDP) administrator Alexander De Croo warned on Thursday, following a visit to the Chernobyl Nuclear Power Station where he inspected damage firsthand. His warning comes after the International Atomic Energy Agency (IAEA) GOV/2025/11 report concluded that the New Safe Confinement (NSC) enclosing Unit 4 can no longer perform its primary safety function of containing radioactive material from the 1986 explosion.

‘Whether it was a deliberate attack or an accident, this is something which is unacceptable,’ De Croo said. ‘Making sure that drones are not flying above that site is one way of avoiding that things like this could happen.’ He called for urgent international action, stressing that Russia had not been acting in line with international humanitarian law and that ‘even in war, there are rules to be followed.’

The Escalating Pattern of Chernobyl Drone Attacks

The IAEA’s assessment, prepared following a comprehensive safety review requested by Ukraine’s State Nuclear Regulatory Inspectorate (SNRIU), found that a drone strike on 14 February 2025 struck the upper part of the NSC arch, causing fire and structural damage. According to the American Nuclear Society, the strike left a hole larger than 500 square feet in the outer cladding, with efforts continuing to extinguish isolated smouldering areas of the structure’s insulation material.

The pattern of incursions has continued into 2026. According to the IAEA’s GOV/2026/7 report, three drones were detected within five kilometres of the site on 20 January 2026, causing the loss of four off-site power lines for the day; two further drones were detected within five kilometres on 5 February; and eight drones were detected within the monitoring area across 13 and 14 February. On 7 June 2026, a Russian drone struck a building storing spent nuclear fuel near Chornobyl, according to NucNet. …………..

The IAEA has maintained a continuous support and assistance mission at the Chornobyl site since January 2023, deploying additional staff in 2025 to conduct its safety assessment of the damaged NSC, as confirmed in IAEA Director General Update 330. Temporary repairs to restore a degree of confinement function are under way in 2026, with support from the European Bank for Reconstruction and Development (EBRD), according to IAEA Director General Update 331. Full restoration remains contingent on the end of the conflict.

The Chernobyl site’s history makes the current position acutely serious. The 1986 disaster, classified as a level 7 nuclear event, occurred after a reactor went out of control during a poorly managed routine safety test, killing 31 people directly. The IAEA projected that radiation released could lead to around 4,000 cancer-related deaths among those within the affected radius, and between 1991 and 2005 documented at least 5,000 cases of thyroid cancer in children under 14 in Belarus and Ukraine, linked to severe radiation exposure………………………………………………………………………………………………………………………………………………..

With the NSC unable to contain radioactive material and drone incursions continuing, the IAEA’s next reporting cycle and any Security Council response to De Croo’s intervention will indicate whether international pressure translates into enforceable restrictions on airspace above the site. https://www.lawnews.co.uk/legal-news/chernobyl-drone-attacks-gamble-with-safety-of-millions-undp-warns/
