Nato will aim to avoid a new arms race with Russia, its secretary general says, after the US formally withdrew from a key nuclear treaty with Moscow.

Axar.az reports citing BBC.

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).

The INF treaty was signed by US President Ronald Reagan and Soviet leader Mikhail Gorbachev in 1987 but its collapse more than 30 years later has raised fears of a news arms race.
