Some 50 people gathered in front of Hungary's embassy in Bulgaria's capital Sofia to protest against Hungary's extradition to Azerbaijan of Ramil Safarov, the murderer of Armenian army officer Gurgen Margaryan, novinite.com reported.

The protesters – members of the local Armenia minority, according to media – sang Armenia's national anthem and chanted "Shame on Hungary!" and "Disgrace!" They also threw small coins at the building of the Hungarian embassy.

New protests are to take place in front of the Hungary's embassy in Sofia, the next one most likely to be scheduled for September 11, when a World Cup qualifier will be played between the teams of Bulgaria and Armenia.

Armenians constitute Bulgaria's fourth largest minority.

Safarov, who was sentenced to life by a Hungarian court for the murder of Armenian office Gurgen Margaryan in February 2004, was extradited to Azerbaijan on Aug 31, 2012 and immediately pardoned by the country’s President Ilham Aliyev.

In response, Armenia suspended diplomatic relations with Hungary.
