Moscow mayor Sergei Sobyanin called on Sunday a bomb attack on a restaurant in the capital the day before a “brutal terrorist act,” but did not say who was responsible. The blast on Saturday evening at the Balzi Rossi, an upscale Italian establishment in central Moscow, killed three people, including the woman bomber, Russian state media said, citing local officials. As of early afternoon on Sunday, there was no further information from Russian authorities, and no one had publicly claimed responsibility. Footage released by Russian state media showed heavily armed law-enforcement officers, several ambulances and other emergency vehicles at the site. So far, Russian authorities have not drawn any connections between Saturday’s blast and these earlier attacks or the war in Ukraine.
