Feb 1 (Reuters) - Elon Musk said on Sunday that moves by his SpaceX company to stop the 'unauthorized' use by Russia of its internet system Starlink seemed to have worked, while Kyiv's defence chief said officials were working on ways to prevent any future use by Moscow.

Russia remains critically dependent on imports in areas at the heart of its war effort, including machinery, drone manufacturing and energy production, the document says. Efforts to expand non-energy exports and build the infrastructure needed to sustain production and overseas supply chains have also stalled.

NATO's ability to deter Russia has taken a huge hit as trust within the alliance erodes. European allies and Canada are investing billions to support Ukraine and boost defense budgets.

The new reality has forced the Kremlin to raise taxes and increase debt, and hovers over peace talks with Ukraine.

Zelenskyy says Ukraine will "take corresponding steps" as Trump says Putin agreed to stop bombing Ukrainian cities for a week.

Russia has been mounting Elon Musk’s Starlink satellite systems on its attack drones to strike deeper into Ukraine, extending their potential flight range to well inside NATO territory, analysts and Ukrainian officials have said.

As losses mount, the pace of Russia's advance has at times been slower than the Battle of the Somme during World War I, a report says.

A new report warns that the number of soldiers killed, injured or missing in Russia's war in Ukraine could reach 2 million by spring
