Tear gas fill the air of a hallway after three opposition MPs released them when they were refused entry into the assembly room by security personnel, in Pristina November 30, 2015. The three opposition lawmakers were arrested in Kosovo on Monday amid chaotic scenes in parliament, filled once more with tear gas in a fresh protest against an accord with former master Serbia. Opposition MPs have been disrupting the work of parliament for two months by releasing tear gas in the chamber each time it tries to sit. They are demanding the government revoke a deal, brokered by the European Union, to grant minority Serbs greater local powers and the possibility of funding from Belgrade. They also oppose a border demarcation deal with Montenegro. REUTERS/Hazir Reka
