International media watchdog Reporters Without Borders, RSF, has called on the Serbian authorities to investigate how much surveillance goes on in the country - after the Serbian news agency Tanjug on February 16 published a response written by the Defence Minister to a never-published opinion piece by a former defence minister.
Prime Minister Boyko Borisov and senior military officers from the United States and Serbia are currently watching the battle firing of the tactical teaching "Shabla 2019".
The demonstrations are also attended by Minister of Defense Krasimir Karakachanov and Defense Chief General Andrey Bocev, BTA reports.
The training includes air defense formations by the Bulgarian Army.
Belgrade's protests ended, and people went home after special forces of the Serbian police took out protesters from the nation's RTS television, TASS reported.
Opposition Leaders Dragan Dzillas and Bosko Obradovic, leader of the Dveri Party, were among the last out of the RTS building. Then the gathered tried to penetrate the building again, but the police pushed them with shields.
