MOSCOW (AP) — A deputy chief of Russia’s military intelligence agency was shot and wounded in Moscow on Friday in an attack that follows a series of assassinations of senior military officers that Russia has blamed on Ukraine.

Lt. Gen. Vladimir Alekseyev was hospitalized after being shot several times by an unidentified assailant at an apartment building in northwestern Moscow, Investigative Committee spokesperson Svetlana Petrenko said in a statement.

She didn’t say who could be behind the attack on the 64-year-old who has served as the first deputy head of Russia’s military intelligence agency, known as the GRU, since 2011.

He was decorated with the Hero of Russia medal for his role in Moscow’s military campaign in Syria and in June 2023 was shown on state TV speaking to mercenary chief Yevgeny Prigozhin when his Wagner Group seized the military headquarters in the southern city of Rostov-on-Don during his short-lived mutiny.

The shooting came a day after Russian, Ukrainian and U.S. negotiators wrapped up two days of talks in Abu Dhabi, United Arab Emirates, aimed at ending the nearly 4-year-old conflict in Ukraine. The Russian delegation was led by Alekseyev’s boss, military intelligence chief Adm. Igor Kostyukov.
