The European Union's naval operations force has landed troops on a tanker in the Mediterranean, European diplomacy chief Kaja Kalla said.
According to her, the ship MV MIDAG is related to Russia. She added that on November 16, the foreign ministers of the EU countries intend to approve new sanctions against Russia.
In August, Vladimir Putin warned the West against a mirror response to the seizure of merchant ships, "and not necessarily in the same waters where attacks on our ships and vessels are planned."
Russia will respond to piracy from Western countries wherever it deems appropriate, including in the Far East, the president added.
