A bomb detonated at a restaurant Saturday in central Moscow, killing at least two people, Russian state media said, citing local officials. The bomber was also killed.
At least 21 people were also injured when the explosive device detonated at the restaurant on Kudrinskaya Square in Moscow, the National Anti-Terrorism Committee said, quoted by Russian state news agency RIA Novosti.
An unidentified woman who attempted to carry the explosive device into the restaurant died in the blast, as did a security guard and a patron, the news agency said.
Ria Novosti reported that the woman attempted to smuggle the bomb into the establishment, but the security guard refused to let her in before the device exploded.
The attack is under investigation, the Moscow Investigative Committee told the news agency.
