Brother of St Petersburg subway blast accused held
The brother of a man accused of organising a suicide bombing on the St Petersburg subway has been arrested, Russia's Federal Security Service says.
The security service, known as the FSB, said it arrested Akram Azimov in a town close to Moscow on Wednesday.
He is being held on suspicion of providing money to his younger brother Abror to prepare for the April 3 subway bombing and of aiding him in contacts with unspecified terrorist organisations.
Abror Azimov was arrested on Monday and charged with organising the attack that killed 14 passengers. At least 45 others were injured in the incident.
The FSB said he is believed to have helped prepare the suicide bomber.
There has been no claim of responsibility for the attack, but the suicide bomber is alleged to have had ties to Islamic extremists.
The bomb was contained in a briefcase. A second explosive device was found and defused.
