A senior Russian military officer, Lieutenant General Vladimir Alexeyev, was rushed to hospital after being shot in Moscow on Friday, investigators said, in the latest of a series of attacks on top military officials.

Alexeyev is deputy head of the GRU, Russia’s military intelligence. His boss, Igor Kostyukov, has been leading Russia’s delegation in negotiations with Ukraine in Abu Dhabi on security-related aspects of a potential peace deal.

The Moscow prosecutor’s office said Alexeyev, who was born in Soviet Ukraine, had been shot several times at a residential building in northwest Moscow by an unknown assailant who fled the scene.

Several senior Russian officers have been assassinated since the start of the war in Ukraine, with Moscow blaming the attacks on Kyiv. In some cases, Ukrainian military intelligence has claimed responsibility.

Since December 2024, three other officials of the same rank as Alexeyev, lieutenant general, have been killed in or near Moscow.

The attacks have angered Russia’s influential war bloggers, prompting questions about why such senior people have lacked adequate protection. In at least two cases, the targets were killed right outside their homes.

The head of the General Staff’s army training directorate, Lieutenant General Fanil Sarvarov, was killed by a bomb placed under his car on December 22.

Alexeyev was responsible for relations between the Defence Ministry and the Wagner mercenary group, led by Yevgeny Prigozhin, which fought in some of the fiercest battles in the early stages of the war in Ukraine.

Prigozhin was fiercely critical of the defence establishment and staged a mutiny in June 2023, when Alexeyev was one of the top officials sent to negotiate with him. The mutiny fizzled out, and Prigozhin died in a plane crash two months later.
