Russia has denied violating a Cold War missiles treaty, following accusations by unnamed officials in President Trump's administration that Russia had deployed a banned cruise missile. A Kremlin spokesperson said on Wednesday that Russia continued to uphold its international commitments. The US state department has made no official comment. The alleged deployment was discussed during Wednesday's Nato meeting in Brussels, the first since President Trump took office. Nato Secretary General Jens Stoltenberg said that any non-compliance from Russia on the arms control treaty would be a ‘serious concern for the alliance’. A New York Times report said that the Russians now have two battalions of the prohibited missiles. Republican senator John McCain responded to the situation by calling on the Trump administration to enhance US nuclear deterrents in Europe. He said Russian president Vladimir Putin was ‘testing’ Mr Trump.
