NATO Secretary General Mark Rutte spoke to Ukraine President Volodymyr Zelenskiy on Thursday to discuss the latest Russian attacks on Ukraine, which have led to widespread power outages in the country.

Russia's "massive" military losses in Ukraine are unsustainable, NATO's secretary general warned with the conflict about to enter its fourth year with no clear end in sight.

Grynkewich stated at Sweden’s National Security Conference that Russia and China are escalating joint patrols in the Arctic, extending their presence from the Russian northern coast to north of Alaska and near Canada.

Up to 25,000 Russian soldiers are being killed every month, NATO Secretary General Mark Rutte said this week.

LONDON -- Britain is discussing with NATO allies how it can help beef up security in the Arctic to counter threats from Russia and China, a government minister said Sunday. Transport Secretary Heidi Alexander said the talks are “business as usual” rather than a response to recent threats by U.S. President Donald Trump to take over Greenland.

Russia also called NATO's military exercises in Greenland "yet another provocation" in the Arctic, as the U.S. moves to take control.

Drones have turned the front line into a kill zone, and made casualty evacuation extremely difficult and dangerous.

U.S. NATO ambassador Matthew Whitaker defends American focus on Greenland amid European backlash, calling Arctic security crucial for continental defense.
