Sweden's coast guard said on Friday that there were no longer any visible leaks from the Nord Stream 1 and 2 gas pipelines in the Baltic Sea, suspected to have been damaged by sabotage.
"During their latest flights over the Baltic Sea, coast guard aircraft have not been able to see any roiling on the sea's surface," the coast guard said in a statement, citing two flights on Thursday and Friday.
Bubbling underwater gas plumes appeared on the water's surface after four leaks were discovered in Sweden's and Denmark's economic zones north of Poland starting on September 26. Initially, they measured between 200 and 1,000 metres (220-1,090 yards) in diameter.
Preliminary underwater inspections back up suspicions of probable sabotage, says Sweden.
The pipelines, which connect Russia to Germany, have been at the centre of geopolitical tensions as Russia cut gas supplies to Europe in suspected retaliation against Western sanctions over Moscow's invasion of Ukraine.
Although the pipelines were not in operation, they contained gas before falling victim to the apparent sabotage.
