According to RBC, the Greek ship demanded by radio communication from the Russian ship to provide information about its cargo and port of destination.

The Greek side warned that the "Adler" is in the NATO-controlled area and will be inspected as part of an international operation to suppress illegal arms transfers to Libya.

It is noted that the Russian sailors agreed to the check.

“Four soldiers of the Greek Navy landed from a military helicopter on the deck of the vessel ... After a conversation with the captain and a visual inspection of the vessel, the fact of finding prohibited cargo was not established,” the NB Shipping Company said.

The company stated that after that the NATO military left Adler, their actions were correct and in compliance with international law.

Earlier, Deputy Defense Minister of Russia Colonel-General Alexander Fomin said that the increased activity of NATO forces near the borders of Russia could lead to serious incidents.
