Two 14-year-old boys were killed when an explosive device detonated in the evening in the Konotop district of Sumy Oblast, according to the statement by Oleh Hryhorov, head of the Sumy Regional Military Administration. The children encountered the dangerous device in a field, suffered severe injuries, and died at the scene, the statement said.

In 2022, Russian forces occupied parts of Sumy Oblast, but Ukraine liberated the region in April. Russia intensified its offensive again in 2025. Today, mines, unexploded ordnance and Russian drones shot down over the region pose a danger, as their warheads can detonate after falling. Overall, 146 children in Ukraine have suffered mine-related injuries, former Interior Minister Ihor Klymenko reported in April. For example, two months ago, an 11-year-old boy and a 15-year-old boy in Sumy Oblast were injured when an explosive device detonated.

Hryhorov expressed his condolences to the parents and relatives of the victims and urged people to remain cautious:

“Please be as careful as possible and remind children: do not approach unknown or suspicious objects, touch them, or try to move them. Take care of yourselves and your loved ones,” Hryhorov said.

Demining efforts continue in Sumy Oblast

On 24 February 2022, Russian forces entered the territory of Sumy Oblast. The first battles in the region took place that same day. In particular, Russian forces attempted to break through to Sumy, but Ukrainian troops repelled the offensive. On 11 April 2022, Ukraine restored control over the entire Sumy region.

As early as 7 June 2022, deminers were working in the Konotop, Sumy, and Okhtyrka districts, according to the Government Portal. That day, they surveyed areas and neutralized explosive devices.

The work of deminers remains deadly dangerous. In September 2024, two pyrotechnicians from Dnipropetrovsk Oblast were hit by a mine while demining Sumy Oblast: one died, while the other was hospitalized. In July 2025, deminer Oleh Petrenko was killed during humanitarian demining operations in Shostka District when a Russian FPV drone detonated, the State Emergency Service of Ukraine reported. Another pyrotechnician was injured, the statement said.

Nevertheless, the work continues despite the danger. In 2025, State Emergency Service deminers in the Sumy Oblast found and neutralized 5,283 explosive devices, the agency said in April. Sumy Oblast ranked sixth among all Ukrainian regions by this figure.

Twenty-two percent of Ukraine’s territory is potentially contaminated with explosive devices — more than 133,000 square kilometers, former Interior Minister Ihor Klymenko reported in April this year. Since the beginning of the full-scale invasion, State Emergency Service and National Police deminers have surveyed more than 248,000 hectares of territory and found more than 1 million 112 thousand explosive devices, the statement said.

Ukraine continues to demine its 132,000 square kilometers of potentially hazardous territory. During the last month, Defense Ministry demining units cleared 1,347 hectares of that liberated territory, the ministry said.

In September, Tymur Pistryuha, head of the Board of the Ukrainian Deminers Association, said that Ukraine is the most heavily mined country in the world — a fact recognized by the international community. The contaminated area continues to grow with every day of the war, Suspilne reports.

Ukraine clears 483,366 explosive devices overall

During the month, Ukraine surveyed and cleared 339.84 hectares of agricultural land, 21.31 kilometers of roads, 40.4 kilometers of railway tracks of mines and explosive remnants of war.

In total, in September, demining specialists detected and destroyed 364 explosive devices. Since the beginning of Russia’s full-scale invasion, 483,366 such devices have been detected and destroyed.

Such missions are conducted by several structures at once. Among them are the Main Directorate for Mine Action, Civil Protection and Environmental Safety, and the Defense Ministry, which engages demining units of the Armed Forces of Ukraine and the State Special Transport Service in clearing liberated territories of explosive remnants of war.

Explosive ordnance disposal units of the National Police of Ukraine and pyrotechnic units of the State Emergency Service of Ukraine are also involved in demining operations.

Those deminers now fly drones fitted with special magnetometers that register changes in the Earth's magnetic field, picking out hidden metal from the air and keeping sappers off ground that may be sown with mines.

New plan for mass demining

To make the process more effective, the government has approved a procedure under which the Ministry of Defense’s Mine Action Center will prepare a single national humanitarian demining plan every year, while the National Mine Action Authority will approve it.

The plan will be prepared according to a clear timetable for everyone involved in the process, including government authorities, demining operators, and local communities. The Mine Action Center will collect data on contaminated areas, local communities' needs, and demining operators' capacities, and use this information to develop humanitarian demining plans.

Ukraine's Third Army Corps says it became the first military unit in the world to use ground robots for mine clearance inside a live offensive, sending the machines ahead of its infantry into the deadliest sectors to keep soldiers out of the line of fire, Censor.NET reported. The corps built the capability from nothing during its Operation Vivaldi counteroffensive in Donetsk Oblast.

Keeping soldiers alive has become the organizing principle of how Ukraine fights, and handing the jobs most likely to kill them to ground robots is how an army that refuses to treat its people as expendable defends the line.

Robots cleared 30 km of routes in two nights

On the Shandryholove axis, the robots cleared 30 kilometers of routes in two nights—work that two companies of sappers would have needed a full week to finish. The corps reported no losses among its sappers there. Announcing the operation's second phase, corps commander Brigadier General Andrii Biletskyi said protecting personnel drives how his troops plan and fight:

"People often ask, but what about our losses? My answer: we minimize them by every possible means. In assault operations, drones and ground robots always move ahead of the infantry," he said.

Robots clear most of the mines and mine Russian routes in return

The corps says it built the system from scratch and scaled it from a single squad up to the entire corps, arguing that manual clearing would be impossible across open terrain swept by fire. Ground robots now lift roughly 60% of the anti-personnel mines in its area of responsibility. They also work in reverse, remotely mining Russian advance routes—one crew can lay up to 200 meters a day, cutting off enemy reserves. The same machines carry frontline logistics, evacuating the wounded and hauling in provisions and equipment.

Operation Vivaldi continues in Donetsk Oblast, where the corps recently air-dropped robots behind Russian lines. Its advance has disrupted Russia's plan to encircle the fortified belt of Donetsk cities. In the second phase, the Third Army Corps liberated Shandryholove and Derylove and took full control of Drobysheve. Across the operation's first two phases, it has retaken 125 square kilometers.

Italy has pledged 1.5 million euros (approximately $1.6 million) to support humanitarian demining efforts in Ukraine, deepening its partnership with the United Nations Development Programme (UNDP) and the Ukrainian government.

The agreement was formalized during a high-level ceremony in Kyiv on June 23 attended by Italian Ambassador Carlo Formosa, UN Assistant Secretary-General and new UNDP Administrator Haoliang Xu, Jaco Cilliers, Resident Representative of the UNDP in Ukraine, and Ukraine’s First Deputy Prime Minister and Economy Minister Yuliia Svyrydenko.

"Demining is not just a technical operation; it is a deeply humanitarian act that combines cooperation and innovation to restore hope in Ukraine," Ambassador Formosa said. "This project is not only a response to the emergency — it’s a step toward recovery. It’s about returning land to farmers, playgrounds to children, and safe roads to families."

The funding will support UNDP’s mine action program, which focuses on clearing land contaminated by mines and explosive remnants of war, ensuring the safe return of land to Ukrainian communities.

The initiative comes as Ukraine continues to grapple with one of the world’s largest demining challenges. According to the State Emergency Service, the total area of potentially mined land has been reduced by over 20% since late 2022. However, approximately 137,000 square kilometers (52,900 square miles) — much of it farmland — remain contaminated. Demining operations are carried out by the emergency service personnel, National Police, Ministry of Defense, and non-governmental organizations.

Currently, 112 certified demining operators, including eight international groups, are active in Ukraine, the State Emergency Service reported on June 24. Their combined capacity includes more than 9,000 personnel, 278 specialized vehicles, and over 13,000 metal detectors.

While significant progress has been made, Ukrainian officials stress that continued international support and funding are critical to accelerating clearance efforts.
