An explosion outside an upscale restaurant at Kudrinskaya Square in Moscow kills people, according to multiple reports. Moscow Mayor Sergei Sobyanin describes the incident as a “brutal terror attack” and says those responsible will be punished. The reporting also notes that, despite the mayor’s characterization, several questions remain about the circumstances of the blast, including what caused it and who may be behind it. Authorities are investigating the attack, but the available coverage does not provide further confirmed details on suspects, motives, or whether any specific group has been identified. The incident is described as occurring in a central area near the restaurant, with the blast drawing public attention and triggering emergency response. While officials label it a terror attack, the broader picture—including the chain of events leading to the explosion and the evidence supporting responsibility—remains unclear in the information provided by the sources.
