President of Serbia Aleksandar Vucic says he would "fight for Serbia with all his heart" during the UN Security Council session on Kosovo, to be held on Monday.

During an unscheduled press conference in Belgrade on Sunday, Vucic announced he would travel to New York on an Air Serbia plane, and "hopes it won't be late" - and noted that he would present "what Serbia thinks" after UN mission in Kosovo (UNMIK) chief Zahir Tanin addresses the Council.

Newly appointed KFOR Commander Major General Lorenzo D’Addario said KFOR is ready to intervene in Kosovo if stability is endangered, Tanjug news agency reported.

General D’Addario told Podgorica-based daily Pobjeda that decision on transformation of Kosovo Security Forces into armed forces is ill-timed.

He added, the North-Atlantic Organization would now have to re-examine its level of engagement with Kosovo Security Forces.

Regional broadcaster N1 reports that Director of the Office for Kosovo and Metohija Marko Djuric told reporters in the Government of Serbia that Kosovo Army for Serbia is an illegal armed formation on the territory of Serbia, formed with an aim of violently changing the borders of the country.

"The decision on its formation aims at violent change of the borders of our country and violation of the established position of our southern province by the Constitution and international," Djuric told reporters.

RTS reports that Serbia will seek today the holding of an urgent session of the UN Security Council due to the worst violation of UN Security Council Resolution 1244 by the Pristina's decision to form a Kosovo army, Serbian Foreign Minister Ivica Dacic said.

"This is the most direct threat to peace and stability in the region and the security of the Serbian people living in Kosovo and Metohija," Ivica Dacic told Tanjug.

At the extraordinary press conference of the Crisis Committee of the four northern Kosovo municipalities, President of Serbian List Goran Rakic ​​said Pristina’s decision to form Kosovo army showed that it did not want peace.

Rakic ​​has called on Serbs from Kosovo and Metohija to remain peaceful, not to fall for provocations.

He stressed that by forming Kosovo army Pristina does not want peace and that KFOR is the only one with the mandate to carry weapons and ensure peace and security.

Head of EU Delegation in Serbia Sem Fabrizi said on Friday that the Kosovo army should be formed in line with the Constitution which does not mean that today’s vote on three laws to transform the Kosovo Security Forces (KSF) is contrary to it, TV N1 reports.

“Our view is clear. The EU shares the opinion of NATO that the transformation has to be inclusive, long-term and in line with the Constitution of Kosovo,” the EU Delegation chief said.

The Kosovo Assembly in Pristina on Friday adopted three draft laws allowing for transformation of the Kosovo Security Forces (KSF) into an army. Several future "soldiers" also walked into the parliament (see video below), B92 reports.

RTS is reporting said that the legislation in question was passed "under accelerated procedure and unanimously." The decision, that comes after years of trying, has been supported by the US and Germany, but is opposed by the EU and NATO, that is currently (through KFOR) tasked with guarding Kosovo's borders.

Today, the Institutions in Kosovo have announced the adoption of the three laws initiating the process of transition of the Kosovo Security Force.

I regret that this decision was made despite the concerns expressed by NATO. While the transition of the Kosovo Security Force is in principle a matter for Kosovo to decide, we have made clear that this move is ill-timed.

Serbian Prime Minister Ana Brnabic said today is a difficult day for her, but that Serbia would continue its path towards peace and prosperity, BETA news agency reports.

She added today’s decision of the Kosovo Assembly to pass the laws on transformation of the Kosovo Security Forces does not contribute to the cooperation in the region.

She underlined Serbia would continue its path towards peace and prosperity since without stable region there is no stable Serbia either.

Tanjug news agency reports that MPs of Srpska Lista do not take part in today’s Kosovo Assembly, session, set to approve laws on the transformation of Kosovo Security Forces into an army.
