Kyiv's security services under strain, 4 September 2026
Summary
A drone strike on the SSU headquarters followed two days of shooting between Ukraine's own agencies in the capital.
What did Kyiv's security establishment look like on 4 September 2026? It was under pressure from outside and from within, in the space of three days.
On 4 September 2026, a Russian drone struck the Security Service of Ukraine (SSU) headquarters in central Kyiv and injured five people. Ukrainian president Volodymyr Zelenskyy said the attack targeted acting SSU head Oleksandr Poklad, who was unharmed.
Shooting between agencies
The strike came after a separate incident that had already drawn attention to the SSU. On 2 September 2026, the SSU and Defence Intelligence of Ukraine (HUR) exchanged fire in Kyiv, and three HUR officers were injured. As described later, the shootout took place in the capital's Dniprovskyi District on the morning of that day.
As reported on 3 September 2026, SSU personnel opened fire on agents of the HUR during a search at an apartment in Kyiv. The search was linked to an arrest against a Russian national fighting for Ukraine, and three people were wounded. Two Ukrainian security bodies were thus in armed confrontation in the capital while the country was at war.
Pressure on the front
The military picture was also difficult. On 3 September 2026, Russian forces said they had captured several settlements in northeastern Kharkiv Oblast and encircled Ukrainian forces. Fighting over the oblast had been under way since 2024, mostly in Chuhuiv and Kupiansk raions, with engagements also in Bohodukhiv, Izium and Kharkiv raions.
A legal move at sea
A different kind of pressure appeared on 2 September 2026, when Norway seized the Russian-owned ship Professor Molchanov near Svalbard. The seizure was meant to enforce a US$4.22 billion compensation award owed to Ukraine's Naftogaz for assets expropriated in Crimea. The case was listed under Norway–Russia relations and the Russian shadow fleet, the network of vessels Russia operates to evade sanctions imposed after its 2022 invasion.
What the sequence shows
Taken together, the reports from 2 to 4 September 2026 show several layers of security strain. A Russian drone reached the SSU headquarters in central Kyiv. Two Ukrainian agencies fired on each other during an arrest-related search. Russian forces claimed gains in Kharkiv Oblast. Meanwhile, Norway moved to enforce Ukraine's financial claim against Russian-owned property.
The drone strike on the SSU headquarters was, by Zelenskyy's account, aimed at the service's acting head, and it hit the same institution whose officers had been in a shootout two days earlier. The attack injured five people and left Poklad unharmed.
