British National Arrested in Ukraine for Alleged Role in FSB Assassination Plot

Ukrainian authorities have detained British national Ross David Cutmore on allegations that he collaborated with Russia’s Federal Security Service (FSB) to carry out assassinations in Ukraine, officials announced. If convicted, Cutmore could face up to 12 years in prison and confiscation of property, according to Ukraine’s Security Service (SBU).

While some reports have described Cutmore as a British army veteran, his military background remains unclear. When questioned about his service record, the UK Ministry of Defense referred inquiries to the Foreign Office, suggesting his claimed military credentials may need verification.

A spokesperson for the UK Foreign, Commonwealth and Development Office (FCDO) confirmed they are “providing consular assistance to a British man who is detained in Ukraine” and remain “in close contact with Ukrainian authorities.” The FCDO emphasized that their ability to intervene is limited, noting they cannot extract British nationals from foreign detention, prevent deportation after sentencing, or interfere in criminal proceedings.

According to Ukrainian security officials, Cutmore arrived in Kyiv in early 2024, initially serving as a military instructor training Ukrainian army personnel. The SBU alleges that after several months, he ceased his instructor work and sought collaboration with Russian intelligence services, motivated by financial gain.

Investigators believe Cutmore initiated contact with Russian operatives by posting in pro-Russian social media groups. The SBU claims he was subsequently recruited by FSB officers in Odesa in September 2024 and paid $6,000 to provide Russia with sensitive information about foreign military instructors and the coordinates of training centers in southern Ukraine.

The case highlights the complex security landscape in Ukraine, where thousands of foreign volunteers have traveled to assist in the war effort since Russia’s February 2022 invasion. President Volodymyr Zelenskyy had made public appeals for veterans to support Ukraine at the conflict’s outset, creating a multinational presence within the country’s defense structure.

Ukrainian authorities further allege that Cutmore received instructions for manufacturing homemade explosive devices, along with coordinates for a weapons cache where he obtained a pistol with loaded magazines. The SBU reports they detained him at his Kyiv residence before he could carry out any attacks.

The accusations against Cutmore include providing Russia with information regarding Ukraine’s military capabilities and preparing for “terrorist attacks,” according to SBU statements. This case appears to be part of ongoing Ukrainian counterintelligence efforts to identify potential security threats amid the continuing conflict.

The detention comes at a particularly sensitive time in the Russia-Ukraine war, with fighting intensifying in eastern regions and international diplomatic efforts seeking pathways to resolution. Security services across Ukraine have remained vigilant against potential espionage and sabotage activities, which Russian forces have reportedly employed alongside conventional military operations.

Neither the SBU, Kyiv’s Prosecutor’s Office, nor the Russian FSB immediately responded to requests for additional comment on the case. The investigation and legal proceedings against Cutmore are expected to continue as Ukrainian authorities build their case against the British national.

The arrest underscores the significant security challenges facing Ukraine as it defends against both conventional military attacks and covert operations after nearly three years of full-scale war with Russia.
