The spokesman for the US National Security Council, John Kirby, warned: "We see a large Serbian military deployment along the border with Kosovo," and highlighted the "unprecedented" installation of artillery, tanks and infantry units. In this sense, the official did not want to comment on the danger of a possible invasion of Kosovo, whose independence Serbia does not recognize and which has been immersed in a spiral of tension for several days, reported the AFP news agency. Furthermore, Kirby stressed that "due to recent events, Kfor", the force deployed by NATO in this former Serbian province, "will increase its presence" in the north of the territory. Kirby indicated that the head of US diplomacy, Antony Blinken, called Serbian President Aleksandar Vucic this Friday to express US "concern" and "highlight the need for an immediate reduction in tensions and a return to dialogue." For its part, the North Atlantic Council authorized this Thursday "the sending of additional forces to address the situation" in that region, according to a statement from the Secretary General of the Transatlantic Alliance, Jens Stoltenberg. The text does not give any information about the type of force it could send, but the British Ministry of Defense assured that it had made a battalion, made up of 500 to 650 troops, available to the Kfor (Kosovo Force). According to the ministry, the First Battalion of the Princess of Wales Royal Regiment arrived "recently in the region" to carry out long-planned military exercises.
