powerful explosion at the upscale Balzi Rossi Italian restaurant on Kudrinskaya Square in central Moscow killed three people and injured around 20 others after what Russian authorities say was an improvised explosive device; officials report that a woman suspected of carrying the IED died along with a security guard and a diner as the blast tore through a summer terrace during a private event, prompting heavily armed police and emergency services to seal off the area and Russia’s National Anti‑Terrorism Committee to open a terrorism investigation.
