Brussels (AFP) – NATO said Tuesday it is “up to Russia” to save a Cold War nuclear arms reduction treaty that the US has threatened to leave, accusing Moscow of breaching the agreement.

“We call on Russia to return urgently to full and verifiable compliance. It is now up to Russia to preserve the INF treaty,” foreign ministers from the 29-member alliance said in a joint statement after talks in Brussels.

Western powers say a Russian missile system developed and fielded over the last five years breaches the 1987 Intermediate Range Nuclear Forces (INF) treaty.
