Russia has denied violating a Cold War-era missiles treaty, following accusations by officials in US President Donald Trump’s administration.
The unnamed US officials said 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 is expected to be discussed during Wednesday’s Nato meeting in Brussels, the first since President Trump took office.
Nato Secretary General Jens Stoltenberg said he would not comment on intelligence reports but added that any non-compliance from Russia on the arms control treaty would be a “serious concern for the alliance”.
The Brussels meeting will be attended by US Defence Secretary James Mattis.
“Nobody has formally accused Russia of violating the treaty,” Kremlin spokesman Dmitry Peskov said in a press briefing.
