Amnesty International is concerned by the reported detention of four health professionals in the Chechen Republic of the Russian Federation. The four men – Abubakar Ismailov, Samrudy Djabrailov, Aslanbek Zelimkhanovich Djankhutov and Mussa Goitaev – are reportedly detained incommunicado in “filtration camps” where, Amnesty International fears, they may be tortured or ill-treated.
