A bomb detonation at a Moscow restaurant killed three people on Thursday, according to Russian state media reports. Security officials said a woman attempted to enter the establishment with explosives but was intercepted by a security guard at the entrance.

The incident occurred during what authorities described as a thwarted attack. The guard's intervention prevented the woman from reaching the interior of the restaurant, but the device detonated during the confrontation at the entrance, killing three people including the guard. Multiple others were injured in the blast.

Russian officials have not yet publicly identified the attacker or disclosed a motive. The bombing marks a rare violent incident in central Moscow, where security typically remains heightened following years of conflict in neighboring regions.

The restaurant attack comes amid ongoing tensions in Russia and increased security concerns across the country. While details remain sparse, the incident underscores persistent threats facing Moscow's civilian population. Authorities have launched an investigation into the bombing and are examining the circumstances surrounding the detonation.

No group has claimed responsibility for the attack as of the latest reports. Russian security services continue gathering evidence at the scene.
