A Russian nuclear submarine has successfully test-fired four inter-continental ballistic missiles in a show of readiness of Moscow’s nuclear forces amid tension with the US.

The Russian defence ministry said the Vladimir Monomakh submarine of the Pacific Fleet launched four Bulava missiles in quick succession from an underwater position in the Sea of Okhotsk.
