As reported by Censor.NET citing Europeiska Pravda, this was announced by Secretary-General of the Alliance Jens Stoltenberg.
He noted he had information that the Russian Navy was assisted in some NATO countries ports. Earlier, military ships of Russia were reported fueled in Spanish ports.
Every nation should decide for itself on fueling and supplying ships in Mediterranean seaports, Stoltenberg said, but he also expressed concerns about the aim of the travel of the Russian Navy.
"The battle group may be used to increase Russia's ability to take part in combat operations over Syria and to conduct even more air strikes against Aleppo," Stoltenberg also said as quoted by Reuters.
"The concern is that the carrier group can be used as a platform for increased air strikes against civilians in Aleppo," he told a news conference.
The battle group, which passed through the English Channel on Friday, is made up of Russia's only aircraft carrier Admiral Kuznetsov, as well as a nuclear battle cruiser, anti-submarine warships and support vessels, likely escorted by submarines, NATO officials said.
The naval deployment, a rare sight since the end of the Soviet Union, is carrying fighter bombers and helicopters and is expected to join around 10 other Russian vessels already off the Syrian coast, diplomats said.
