NUCLEAR war shelters are being readied in Sweden to prepare for a surprise Russian attack, according to reports.

The Swedish Civil Contingencies Agency (MSB) has reportedly been ordered to carry out a review this year of bunkers the coming weeks as the Scandinavian country also reintroduces military service.

A system of 65,000 bunkers was established in the Cold War to protect the population from nuclear war with the Soviet Union.

According to MSB, the bunkers currently protect against blast and radiation as well as chemical or germ warfare.

With a distinctive logo, they can easily be located by civilians seeking shelter.

But with fears growing over threat posed by Vladimir Putin and his resurgent Russia they are being reviewed to make sure they are ready.

Russian military drills in the region have raised fears among neighbouring nations that an attack could happen in the coming months.

Civil defence measures are therefore being stepped up, especially in the Island of Gotland where Sweden has already re-opened a garrison.

Swedish broadcaster Sveriges Radio reported that Mats Berglund had ordered a review of the island's 350 civilian bunkers.
