"Today, the FSB operatives detained Crimean Tatar Emil Mukhteremov in Feodosia and took him to the local FSB office, where he managed to make a call to his friend and inform of his whereabouts. Shortly, they took Mukhteremov to a field near Zybino village, Ichkinsky (Sovetsky) district, forcing him to dig a grave, threatening to bury him there. Then the FSB operatives left, leaving Emil in the said location," Chubarov wrote Wednesday.

As UNIAN reported earlier, the occupation authorities had not ceased repression against pro-Ukrainian and Crimean Tatar activists since the Crimea annexation. 17 people are reported missing, 12 have been killed, and 39 are being kept behind bars as political prisoners, 10 of whom have already been convicted.
