STOCKHOLM, Sept 27 (Reuters) - Sweden's Maritime Authority said on Tuesday it had issued a warning of two leaks on the Russian-owned Nord Stream 1 pipeline in Swedish and Danish waters, shortly after a leak on the nearby Nord Stream 2 project was discovered.

"There are two leaks on Nord Stream 1 - one in Swedish economic zone and one in Danish economic zone.

They are very near each other," a Swedish Maritime Administration (SMA) spokesperson told Reuters.

On Monday, Danish authorities asked ships to steer clear of a five nautical mile radius southeast off Bornholm after a gas leak from the defunct Nord Stream 2 pipeline drained into the Baltic Sea.

Later the same day, the operator of the Nord Stream 1 pipeline, which ran at reduced capacity from mid-June before shutting down completely in August, also disclosed a pressure drop on both lines of the Nord Stream 1 gas pipeline.
