Russian President Vladimir Putin on Thursday said the “unprecedented sabotage” against the Nord Stream gas pipelines was “an act of international terrorism,” the Kremlin said in a statement.

Putin made the remarks in phone call with his Turkish counterpart Tayyip Erdogan. He also said it was necessary to fulfil an internationally-brokered deal on Ukrainian grain exports, including the removal of barriers for Russian food and fertilizer supplies to the global markets, the Kremlin said.
