The UN secretary general has warned that the world has lost “an invaluable brake on nuclear war” with the expiry of a cold war-era arms control treaty on Friday.
“This will likely heighten, not reduce, the threat posed by ballistic missiles,” António Guterres told reporters, adding that he was concerned about rising tensions between nuclear-armed states.
Both Jens Stoltenberg and US Secretary of State Mike Pompeo have blamed Russia for the Cold War treaty’s collapse.
Nato and the US accuse Russia of violating the pact by deploying a new type of missile, which Russia denies.
The Intermediate-Range Nuclear Force banned missiles with ranges between 500 and 5,500km (310-3,400 miles).
