The Basmanny district court ruled that Saidakram Rajabalizoda, Dalerjon Mirzoev, Muhammadsobir Faizov, and Shamsiddin Fariduni must stay in custody until at least August 22. Hours later, the court extended the pretrial detentions of four other Tajik citizens accused of assisting in the attack. Several other Tajik nationals and a Kyrgyz-born Russian citizen were arrested for their alleged involvement in the attack. To read the original story on RFE/RL's Russian Service, click here.
