A powerful explosion ripped through a restaurant in central Moscow late Tuesday, killing three people and injuring 21 others, authorities reported. The blast occurred at approximately 10:30 PM local time, causing extensive damage to the upscale establishment.

Emergency services and law enforcement quickly cordoned off the area as rescue efforts began. The cause of the explosion is currently under investigation, but preliminary reports suggest it may have been deliberate.

Moscow Mayor Sergei Sobyanin visited the scene and described the incident as a "brutal terrorist act." He vowed that authorities would do everything possible to find those responsible and bring them to justice. "We will not rest until we find the perpetrators of this heinous crime," Sobyanin stated.

Of the 21 injured, several are reported to be in critical condition. They have been transported to local hospitals for treatment. The number of casualties is expected to rise as rescue teams continue to sift through the debris.

This incident has sent shockwaves through the capital, raising concerns about security. While officials have not yet officially classified the event, the mayor's strong condemnation indicates a belief that the explosion was not accidental.

Investigators are reportedly examining all possible motives, including potential links to extremist groups or organized crime. The restaurant was known for its luxurious ambiance and attracted a wealthy clientele, which could also be a factor in the investigation.

Further details are expected to emerge as the investigation progresses. The public has been urged to remain calm and cooperate with authorities. The incident has prompted increased security measures in public spaces across Moscow.

This bombing marks one of the deadliest attacks in the city in recent years and underscores the ongoing challenges of maintaining security in major urban centers. Officials are working to provide support to the victims and their families.
