Russia's President Vladimir Putin admits that the country's security organization failed in connection with the murder of Russian General Igor Kirillov in Moscow on Tuesday.
Our intelligence services missed these attacks. They missed these attacks. This means that we must improve this work. We cannot allow such very serious mistakes to happen, he says at his annual press conference on Wednesday.
Igor Kirillov, the highest chief of Russia's radiological, chemical and biological defense, was killed in Moscow on Tuesday in a deed that Ukraine has taken responsibility for.
