Ukraine calls for Western arms after Russia pullback

STORY: As thousands of Russian troops pulled back from Ukraine's northeast, Kyiv's demining unit said on Monday it had begun clearing out villages there of explosives left behind.

Videos obtained by Reuters showed the unit said to be at work, which Reuters could not independently verify.

President Volodymyr Zelenskiy said Kyiv's forces have successfully been retaking land from Russia since the start of September.

“Since the first days of September and until today, our warriors have liberated more than 6,000 square kilometers of the territory of Ukraine in the south and in the east. The advances of our forces continue.”

Russia's losses in the northeast, including its main base there on Saturday, mark its worst defeat since the early days of the war.

But Moscow troops also fired missiles at power stations as they pulled back, which have caused blackouts.

Kharkiv's governor said at least one was killed and several others wounded.

Moscow did not comment on the attacks, but has previously denied intentionally attacking civilians.

Zelenskiy called on the West to speed up deliveries of weapons systems to consolidate control over the territory.

"Yesterday and today, the Russian army struck the Ukrainian energy infrastructure. Hundreds of thousands of Ukrainians found themselves in the darkness – without electricity. Buildings, hospitals, schools, communal infrastructure."

Washington and its allies have provided Ukraine with billions of dollars in weapons that Kyiv says have helped limit Russian gains.

U.S. Secretary of State Antony Blinken said Ukraine's forces have made significant progress with Western support.

“What they have done is very methodically planned out and of course it's benefited from significant support from the United States and many other countries in terms of making sure that Ukraine has, in its hands, the equipment it needs to prosecute this counteroffensive.”

Russia has taken control of around a fifth of Ukraine since its troops invaded in February.

Moscow calls its actions a special military operation to demilitarize and "de-nazify" Ukraine.

Zelenskiy urged the West to continue their partnership to defeat what he called 'Russian terror" on Monday.
