Lithuania says a Ukrainian anti-government activist shows signs of being tortured.
In a statement on February 4, the Lithuanian Foreign Ministry said Dmytro Bulatov "has clear signs of long-term torture and cruel treatment on his body."
The statement called for an independent probe, noting Ukraine is a signatory to a UN convention against torture.
"The European Union has to demand Kyiv to launch a thorough and independent investigation into these and other related offenses, and take steps to punish the perpetrators," it concluded.
The 35-year-old Bulatov arrived in Vilnius late on February 2, hours after a Kyiv court ruled he could leave the country for medical treatment.
Bulatov went missing on January 22 and resurfaced a week later, heavily bruised and with part of an ear cut off.
Images of his bloodied face sparked international outrage, with the European Union's foreign policy chief Catherine Ashton saying she was "appalled by the obvious signs of prolonged torture."
The leader of the "Automaidan" movement, Bulatov organized motorcade protests outside President Viktor Yanukovych's sprawling country estate near Kyiv and has been targeted by police.
