Belarus is believed to have carried out its first execution of the year.
Homel resident Syarhey Vostrykau, who was found guilty of rapes and murders involving extreme brutality, was most likely executed last month on either April 13 or April 29, the Belarusian human rights center Vyasna said in a report posted on its website.
"Representatives of the group Human Rights Activists Against the Death Penalty in Belarus have learned that the death sentence handed out to Homel resident Siarhei Vostrykau has been carried out. His mother has received a relevant report from the Homel Regional Court," Vyasna said on its website on May 5.
Judges in the regional court in the southeastern city of Homel found Vostrykau, 33, guilty in May of last year of kidnapping, raping, and murdering two women in 2014 and 2015. The case was heard behind closed doors.
Belarus remains the only country in Europe which still applies the death penalty. The execution is carried out by firing squad.
The European Union issued a statement reaffirming "its strong opposition to capital punishment in all circumstances."
"The continued application of the death penalty goes counter to Belarus's stated willingness to engage with the international community, including the European Union, on the matter and to consider the introduction of a moratorium on the use of the death penalty," EU spokeswoman Maja Kocijancic said in a May 6 statement.
"The European Union urges Belarus...to commute the remaining death sentences and to introduce without delay a moratorium on the death penalty as a first step towards its abolition," Kocijancic said.
Belarus carried out four executions last year. Before 2016, an execution had not been carried out under the Belarusian legal system since November 2014.
