The incident has escalated diplomatic tensions between Moscow and Baku

The UN Human Rights office (OHCHR) announced on Friday it is "concerned" about press freedom in Azerbaijan following the arrests of Russian journalists. Moscow has denounced the detentions as "unlawful."

On Monday, police in Baku raided the local office of Russia's Sputnik news agency, detaining two senior editors and five others. The news agency has been accused of fraud, illegal business activity, and money laundering - charges Sputnik dismissed as "absurd." A Ruptly editor was also detained while filming outside the building.

"[UN] High Commissioner Volker Turk has repeatedly stated that he is concerned about the situation with press freedom in Azerbaijan and the detention of journalists," OHCHR spokeswoman, Ravina Shamdasani, told RIA Novosti. "We are monitoring this situation closely and are gathering more information before we can comment in more detail."

Following the arrests, Moscow accused Azerbaijan of "hostile actions and unlawful detention of Russian journalists" and demanded their immediate release. Russia's consul in Baku met with the detainees on Thursday and was reportedly satisfied with their condition.

Tensions between Moscow and Baku spiked after recent police raids on an alleged organized crime group in the Russian city of Ekaterinburg. The group, composed of Russian nationals of Azerbaijani origin, is accused of a string of gang assassinations and contract killings dating back to the early 2000s.

Two elderly male suspects died during the police operation, with the preliminary assessment indicating that at least one of them suffered heart failure. The incident sparked outrage in Baku, which accused Moscow of deliberately targeting people of Azerbaijani descent and claimed that the two men had been murdered while in custody.

Azerbaijani authorities arrested eight more Russian nationals on Tuesday, claiming they belonged to a cybercrime and drug trafficking group operating from Iran. Russian outlets identified two as IT specialists who left Russia after the start of the conflict with Ukraine. One suspect was reportedly a tourist.

Kremlin spokesman Dmitry Peskov said Russia is negotiating the release of its nationals with Azerbaijan through law enforcement channels. He stressed that Russia would defend the "legitimate interests" of its citizens using "all available means."

Speaking to reporters on Friday Foreign Ministry spokeswoman Maria Zakharova suggested the rift between the two historically close neighbors has been influenced by outside forces. Friendly ties remain important for both Moscow and Baku, she stressed, while calling for a probe by Russia's Investigative Committee into the deaths of the suspects during the Ekaterinburg raid.
