If the Russians want to go to Kyiv, they have to get past Sergei Bayta and his men.

The 52-year-old man has been at his post in Brovary since the beginning of the war.

It's one of the main checkpoints in the suburb northeast of the capital.

The front is getting closer.

A week ago, Bajta almost died here.

The Russians fired six rockets in his direction.

Two of his colleagues were killed and eight injured.

A burned-out car stands at the side of the road, reminiscent of the impact, next to a destroyed tank.

Gunshots can be heard again.

Anxious, the Ukrainian soldiers run around and try to stay up to date over the radio.

The Russians can strike at any moment.

Sergei Bajta will not give way.

He's here to defend his post.

He even brought his eldest son with him.

He is now fighting alongside local Ukrainian militias and regular forces.

The equipment is not bad.

They have new weapons and proper uniforms, even anti-tank mines are placed around the post.

They could blow up any Russian military vehicle in an instant, says one.

The Ukrainians are determined

"We can only defeat our enemies together," says Bajta resolutely.

But he can't hide his nervousness.

Russia's army is advancing ever further towards the center of the Ukrainian capital.

The breaks between the air raids are getting shorter and shorter.

And then there is the Russian military convoy, which is said to be more than 60 kilometers long and is stuck somewhere outside of Kyiv.

According to Pentagon estimates, almost all of the invasion troops that Russia had massed on the borders with Ukraine are now in the country.

But the Ukrainians are determined.

They want to win and everyone helps.

Bajta says: "There is no alternative anyway."

Around twenty volunteers have set up a small tent next to Bajta's checkpoint.

Fresh meals are prepared here, warm soups, fresh salads and even cakes.

Outside, the helpers have lit a small fire in an empty oil drum, which the soldiers use to warm their hands during their short breaks.

Few people come by to pass Bajta's checkpoint heading north.

Most are fleeing south to avoid Russian shelling, or heading west.

The UN now assumes that more than two million refugees have left the country.

Thousands flee every day.

A few kilometers west of Brovary, in the Kiev suburb of Irpin, fierce fighting has erupted in recent days.

Several civilians were killed and entire city blocks were destroyed.

At least four people died from gunshot wounds after trying to get to safety over a collapsed bridge.

A dead man has been lying next to his bicycle on the remains of the bridge for days.

Even during the evacuations, the shelling didn't stop.

Up to 3,000 people are said to have left the small suburb of the capital, and thousands are still stuck.
