Belarus President Alexander Lukashenko has threatened to deploy nuclear weapons on NATO nations if he is faced with aggression, amid heightened tension on the country's border with Poland. Warning the West in an interview with state-run BelTA, the Belarusian leader said he would deploy nuclear weapons 'immediately once aggression is launched against us'. 'If aggression against our country is launched from the side of Poland, Lithuania, Latvia, we will immediately respond with everything we have,' he said.
