NATO chief Jens Stoltenberg said Thursday it was "not too late for Ukraine to prevail" against Russia as long as its allies carry out promises to deliver more weapons.

Russian Deputy Foreign Minister Sergei Ryabkov warned on Thursday that NATO nuclear facilities, if permanently located on the Polish territory, will become a military target for Russia."The expansion of the practice of joint NATO nuclear missions - regardless of who becomes that country or those countries that can join those already participating in this practice - is of a purely destabilizing nature.
