GEOFF BENNETT: Russia launched nearly# 400 drones and 29 missiles at Ukraine## overnight.

The full-scale invasion and# war will enter its fifth year next week.## Russia has repeatedly targeted# Ukraine's energy infrastructure,## leaving millions there without heat# or electricity for weeks at a time.

Producer and videographer Amanda Bailly# in Kyiv and Nick Schifrin report now## on residents of Ukraine's capital# under fire in record-setting coal.

NICK SCHIFRIN: In Kyiv, this# is a dark, bitter winter,## a once-bustling European capital.

Now the# night streets lie mostly desolate and cold,## a city whose homes look as Russia wants# them, empty, its residents living in shadows;## 73-year-old Lyudmila Bachurina cooks in her 19th# floor apartment by flashlight and gas burner.

This winter, the temperatures dropped# to minus-14 degrees Fahrenheit.## The windows are lined with ice.

She helps# her daughter stay warm.

The power plants## here provide both light and heat.

They# have had neither for up to 17 hours a day.

LYUDMILA BACHURINA, Kyiv Resident (through# translator): I'm tired.

It's really tiring,## to be honest, when you don't go# outside and you don't see the sun,## when there's no light and you# can't just go down to the store.

OLENA JANCHUCK, Kyiv Resident: When# my husband is at work, my mother and## I are dealing with all this together.# My mother and I, we support each other.

NICK SCHIFRIN: There is no limit to the support# that 63-year-old Vasyl Ivanovych will give to## his 40-year-old son, Taras (ph).

But# in blackouts, the burden is heavier.

Taras is disabled and can't walk.

And# no electricity means no elevator.

Vasyl## says he feels like the war has set them back# hundreds of years.

Inside, no power or heat,## so the warmth comes from Vasyl caring for his# son and from the orthodox Christmas trimmings.

But this family is especially vulnerable.# The closest shelter is two blocks away.## And sometimes the missiles land without# warning.

Since the start of the year,## Ukraine says Russia has attacked the energy# grid more than 217 times, including at## least six strikes that damaged all three of# Kyiv's major combined heat and power plants.

It's not all the time.

Vasyl Ivanovych# invited us back when the family had## power.

He used to work at the local# subway station.

Now he is his son's## full-time caregiver.

He keeps a car# battery in the kitchen for charging.

VASYL IVANOVYCH, Kyiv# Resident (through translator):## When people are left without gas and# electricity, I'm sorry, but it's very## difficult, especially children, pensioners,# the elderly and people with disabilities.

NICK SCHIFRIN: He shows himself# in younger days and his family,## his grandfather wearing a Soviet uniform.# Today, he calls Russians terrorists.

VASYL IVANOVYCH (through translator): I# can't imagine these children will grow## up and remember these times, Russia and# these people who did all this.

And I'm## not even talking about those who have# seen someone die with their own eyes.

NICK SCHIFRIN: And yet Ivanovych# maintains his humor and appetite,## even if he knows the power is not reliable.# He starts comparing today to Soviet times.

VASYL IVANOVYCH (through translator): Who# knows what's better at the end?

Oh, the## power just went out.

The elevator isn't# working.

There's no light.

But that's OK.

DONALD TRUMP, President of the# United States: Because of the cold,## extreme cold.

They have the same that we do.

NICK SCHIFRIN: Last month at a Cabinet meeting,## President Trump announced a deal# with Russia to spare Ukrainian power.

DONALD TRUMP: I personally asked President Putin## not to fire on Kyiv and the# cities and towns for a week.

NICK SCHIFRIN: That was Thursday, January# 29.

Three days later, on February 1,## a Russian drone hit a bus in Southeast# Ukraine.

The strike killed 12 coal miners,## considered members of Ukraine's energy# sector.

And then, two days later,## February 3, Russia's largest strike on Kyiv# so far this year damaged two power plants.

VOLODYMYR ZELENSKYY, Ukrainian President (through# translator): They want to take advantage of the## cold because they cannot subjugate us with their# assaults.

Every Russian st.. energy sector, but also those leaders who talk# to Russia and receive continued war in response.

NICK SCHIFRIN: That continued# war has forced millions in Kyiv## to fend for themselves in subzero# temperatures, often for weeks at## a time.

But Ukrainians are resilient and# sometimes turn the cold into celebration.

(MUSIC) NICK SCHIFRIN: A deejay led a rave on Kyiv's# frozen Dnipro River, dancing for defiance,## because, just hours before, Russia had launched# 375 drones and 21 missiles at Kyiv and Kharkiv,## leaving 1.2 million Ukrainians without power.

The strikes and blackouts are so common, Kyiv# created invincibility points, fitted with heat,## power, water and food, a tent where Kyiv# residents can find brief distraction## from the war; 79-year-old Vyacheslav# Piontovsky and his 78-year-old wife,## Kateryna, live on the 12th floor# of a nearby apartment building.

They have come for some much-needed heat and# to recharge their phones and their resolve.

KATERYNA PIONTOVSKYA, Kyiv Resident# (through translator): We stand strong## because we want victory.

Nothing will break us,## not the cold or hunger.

We're ready to# survive anything.

We're not giving up.

NICK SCHIFRIN: But the relentless attacks are too# much to bear for others like Natalia Shponarska.

NATALIA SHPONARSKA, Kyiv Resident# (through translator): Emotionally,## it's the fifth year.

We can't keep coping.# .. NICK SCHIFRIN: It is hard for her 8-year-old son,## Mark, to watch his mother cry.

But in this# tent with 10-year-old Nastya (ph), at least## the family can stay warm.

They# haven't had heat for three days.

NATALIA SHPONARSKA (through translator):# At home, there is no power, no water,## no heating.

We live on the 16th floor.# It's so cynical what that jerk Putin## says about wanting peace with Ukraine.# He kills every day.

This is his peace?

NICK SCHIFRIN: This is not peace.

This is# war.

And war can be cold, dark and relentless.
