(QHA) -

The Council of Europe [official website] said Monday that Russia must investigate the deaths and abductions of activists in Crimea and ensure that the rights of minorities and media are respected.

A 16-page report by Europe's Commissioner for Human Rights Nils Muiznieks documented cases of three missing civil society activists and the deaths of local residents since Crimea joined Russia.

The report highlighted serious human rights violations that have occurred in Crimea since February and called on Russia to investigate and hold accountable those responsible.

The report voiced concern over the treatment of Ukrainians and Crimean Tatars. It also noted that freedom of speech has been undermined in Crimea in recent months.
