A homemade bomb exploded outside an upscale Moscow restaurant on Saturday, killing three people and injuring 21 others [1], [2].

The attack targeted a high-profile location in the capital, signaling a potential security breach in a city heavily fortified against external threats. The blast occurred during a private event at Kudrinskaya Square, one of the city's iconic Stalin-era skyscrapers [1], [3].

Mayor Sergei Sobyanin, acting as a spokesperson for Moscow authorities, said the incident was a "brutal terror attack" [4]. The explosion took place approximately three kilometers from the Kremlin [1].

Official reports indicate that the fatalities include two victims and a woman suspected of delivering the explosive device [2]. The blast caused significant damage to the venue and resulted in 21 injuries [2].

RIA Novosti said that a homemade bomb exploded during a private event [2]. While the device has been identified as homemade, authorities have not yet clarified the specific motive behind the attack [2], [4].

Emergency services responded to the scene at the Kudrinskaya Square skyscraper to treat the wounded and secure the perimeter. Investigators are currently examining the remnants of the device to determine its origin and the identity of those involved in the planning [1], [2].

"This is a brutal terror attack,"

The proximity of the attack to the Kremlin and the targeting of a high-end venue suggest an attempt to project instability within the heart of the Russian capital. By using a homemade device delivered by a suspected operative, the perpetrators demonstrated an ability to bypass security at a prominent landmark, potentially forcing a tightening of security protocols across Moscow's administrative center.
