An improvised explosive device detonated at a restaurant Saturday in central Moscow killing two people, Russian state media said, citing local officials. The suspected bomber was also killed, officials said. 

At least 21 people were also injured when the IED 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.
