Tensions rise in Kosovo-Serbia conflict as NATO prepares for troop deployment.

Serbian President Aleksandar Vucic has called on Kosovo authorities to withdraw "alleged mayors" in northern Kosovo to defuse a crisis that has sparked violence. Meanwhile, Kosovo's President Vjosa Osmani said on Thursday that Serbia needs to stop its activities aimed at destabilising Kosovo in order to end the violence in the north of the country. NATO chief, Jens Stoltenberg, said on Thursday that the alliance was prepared to deploy more troops to Kosovo to quell the violence, adding that the first 700 reinforcement troops were on the way there.
