A decision to change the flag waving from a tall pole at at the entrance to Pristina, at the place known as "the roundabout", has divided the public in Kosovo.
Up until Tuesday, the red and black Albanian national flag waved from the pole - but Kosovo Prime Minister Ramush Haradinaj then gave an order to replace it with Kosovo's own flag.
Drita Hajdari told a debate in Pristina on Wednesday evening that Kosovo is obliged to back the new Specialist Chambers, set up in The Hague to prosecute former Kosovo Liberation Army fighters for wartime and post-war crimes.
"The issue of war crimes cannot be an isolated issue for Kosovo alone," Pristina-based prosecutor Hajdari said.
Albin Kurti, a member of the Kosovo Assembly from the opposition Self-Determination, has been arrested.
The arrest took place in front of the Assembly, Tanjug is reporting on Friday, citing RTK2.
Two other Self-Determination members of the Assembly, Albulena Haxhiu and Donika Kadaj-Bujupi, have also been arrested.
Kosovo police arrested three Vetevenedosje MPs, Albin Kurti, former leader of Vetevendosje, Albulena Haxhiu and Donika Kadaj Bujupi, at around 10am on Friday in Pristina while they were going to parliament to attend a session.
