Two young Belarusian men -- Dzmitry Kanavalau and Uladzislau Kavalyou -- are on trial on charges of masterminding a bombing attack in the Minsk subway in April that killed 15 people. Before their trial opened, Liubou Kavalyova, the mother of Kavalyou, said her requests to meet with her son in detention have been rejected. (RFE/RL's Belarus Service)
