Russia's latest missile strikes hit targets including gas fields, industrial infrastructure and residential buildings.

Our correspondent Catherine Bureau hunger is in the Ukrainian capital, Kiev.

Ukraine is still trying to assess the damage from yesterday's widespread nationwide missile strikes across Ukraine.

We understand in the city of Zaporizhia, Zaporizhia region officials say seven people there died when the missile hit a residential building in Dnipro city missiles hit and industrial plants and 14 people were injured, including a teenage girl.

But the wider impacts.

Looking more broadly at Ukraine has been the impact on energy supplies.

We understand that there were strikes on gas facilities in the eastern part of Ukraine, in the southern city of Nikopol, thousands of homes were knocked off the power grid.

Following strikes by Russia, I'm speaking to you from Kiev and here one of the electricity companies said the capital experienced one of its biggest energy shutdowns because of these strikes, it's minus three degrees here in Kiev and this would be a big concern for families who are right now trying to stay warm and get some electricity into their homes.

And it was only this time yesterday that we were looking at live pictures of the first snowfall of the winter there in Kiev.

Catherine.

I mean, it's not just the power is it?

It's also water facilities and a real threat to the availability of drinking water for people.

It's just so basic.

Exactly.

And that's why the United Nations is warning that should these strikes continue, it's going to make the humanitarian crisis here in Ukraine, as you can imagine, it's already bad because of the war.

It's just going to make things even worse.

And that's because electricity is really the backbone of services here in Ukraine.

It powers hospitals, As you say, it also helps to pump water into people's homes.

And we've seen some families having to go out with plastic bottles to collect water on the sides on the street.

I spoke to one woman who says, she's lucky that she has a borehole on her street.

So when there's a power shutdown, she just nips out and then is able to fetch water.

But it really isn't the way that people should be living.

And that's really the concern for aid agencies now, who are worried about what could happen as it gets colder here.
