The Kremlin has issued a stark warning following the attack on a gas pipeline in Serbia, describing the situation as potentially very dangerous and raising alarm about energy security across the Balkans.

Kremlin spokesperson Dmitry Peskov said Moscow views the incident with "extreme concern" and called for a thorough investigation. The pipeline, which carries Russian natural gas through Serbian territory, sustained significant damage in what authorities believe was a deliberate act of sabotage.

Serbia's President condemned the attack and announced the deployment of additional security forces to protect critical energy infrastructure throughout the country.

The incident has sent shockwaves through European energy markets, with natural gas prices rising sharply on fears of further disruptions to supply routes through southeastern Europe.
