Russia produces as much ammunition in three months as NATO does in a year, NATO Secretary General Mark Rutte has warned. Speaking at the Chatham House think tank in London on Monday, Rutte called on the alliance to urgently ramp up weapons production.

Russia is determined to test the resolve of the NATO alliance, including by extending its confrontation with the West beyond the borders of Ukraine, the Germany's foreign intelligence chief told the Table Media news organization.

The head of NATO says members need to increase their air and missile defenses by 400% to counter the threat from Russia and warns that Moscow could be ready to attack the military alliance within five years.
