NATO says damage to the Nord Stream pipelines is of "deep concern" and any deliberate attack against allies' critical infrastructure would be met with a united and determined response.

It comes as a fourth leak has been reported off southern Sweden, the country's news agency said.

Sweden's coastguards told the TT news agency they have a vessel on the site of the leak.

All four detected leaks are in international waters – two near Sweden and two near Denmark.

The Nord Stream pipelines run through the Baltic to transport gas from Russia to Germany.

According to NATO, "all currently available information indicates that this is the result of deliberate, reckless, and irresponsible acts of sabotage".

The military alliance said the leaks are causing risks to shipping and "substantial" environmental damage.
