NATO plans to boost its Response Force, the alliance's secretary-general, Jens Stoltenberg, said, adding that two more headquarters are to be created in Eastern Europe, in Hungary and Slovakia."Today I expect us to approve the establishment of two more such headquarters in Hungary and Slovakia. They will ensure that our forces can move quickly and effectively if they need to deploy," NATO's Secretary-General told journalists in a press briefing Thursday.The alliance will also "give final approval to the military concept" for the NATO Response Force to make it "bigger, faster and more capable", Stoltenberg said after the defense ministers' meeting.Established in 2003, the NATO Response Force is a high readiness force comprising of land, air, sea, and special forces units which are capable of rapid deployment. It is designed to perform a range of tasks, including immediate defense response, crisis management, peace support operations, disaster relief, and the protection of critical infrastructure.According to Stoltenberg, the military alliance is currently facing many challenges, one of them is refugee crisis which he called "a tragic result of the turmoil we see to our south."In the meantime, Maria Zakharova, the Russian Foreign Ministry's spokesperson, said that NATO actions won't contribute to stabilization of the situation in Europe.
