Sweden has released a sonar image it says is proof that a foreign submarine entered its waters in October.

The grainy image shows underwater tracks allegedly left by the vessel.

Several sightings of an unidentified object near Stockholm sparked a huge search and Sweden's biggest military operation in years.

Naval vessels and planes searched waters near the capital but were unable to identify any intruding vessel or say which country was responsible.

Suspicion fell on Russia, but its defence ministry denied any of its ships were involved.

"The military can confirm that a small U-boat breached Sweden's territorial waters," the head of Sweden's armed forces, Gen Sverker Goransson, told a news conference.

Prime Minister Stefan Lofven warned against any further incursions.

"We will defend Sweden's territorial integrity with all available means," he said.

Cold War echoes

Soviet submarine sightings caused security alerts in Sweden during the Cold War in the 1980s.

In one incident, a Russian sub loaded with nuclear torpedoes ran aground near a Swedish naval base in 1981.

The latest search was called off without finding or bringing any vessel to the surface.

Sweden reportedly intercepted a distress signal in Russian, but Russia suggested it could have been a Dutch vessel, something denied by the Netherlands.

The episode raised fears about Russia's intentions in nearby states, following Moscow's role in the Ukraine crisis.

Sweden is not part of Nato but has tightened ties with the alliance. It is also increasing military spending.
