Russian courts have sanctioned the arrests of the eight suspects who have been detained in connection with the deadly April 3 bombing in the St. Petersburg subway.
A St. Petersburg court on April 7 remanded six of the suspects into custody for at least two months as the investigation is carried out.
In Moscow the same day, two other suspects -- a man and a woman -- were remanded to pretrial detention.
The eight are accused of unspecified involvement in the subway bombing, which killed 14 people -- including the suspected bomber -- and injuring around 50.
All the suspects are from Central Asia, and all deny any involvement in the attack.
Police have identified Akbarjon Jalilov, an ethnic Uzbek who was born in Kyrgyzstan and held Russian citizenship, as the suspected bomber.
