(QHA) -

Amnesty International says authorities in Crimea have failed to investigate a series of abductions and torture of their critics since Crimea seceded from Ukraine and joined Russia a year ago.

In the fresh report released March 18—exactly a year after Russia took Crimean peninsula from Ukraine—Amnesty International cites "violations of the rights to freedom of expression, assembly and association in Crimea [and] highlights human rights abuses by the de facto authorities, including the failure to investigate a series of abductions and torture of their critics, and their unrelenting campaign of intimidation against pro-Ukrainian media, campaigning organizations, Crimean Tatars and other individuals critical of the regime."

"One year on from Crimea’s annexation, the attitude of its de facto authorities and their Russian masters can be summed up simply -- like it or leave or shut up," said John Dalhuisen, Amnesty International’s director for Europe and Central Asia.

Amnesty said since the annexation of the Black Sea peninsula, at least seven people have been abducted, with their fates unknown. At least one other abducted individual has been found dead, with signs of torture.

The global human rights watchdog said it has documented the disappearances of three Crimean Tatars, adding that in none of these cases was anyone held accountable.
