More than a week into Russia's invasion of Ukraine, its troops have made significant advances but have so far failed to take the capital Kyiv.

Here are the latest developments on day 10 of the invasion:

  • Russians continue attempts to encircle the capital Kyiv
  • Temporary ceasefire agreed in Mariupol and Volnovakha
  • But Ukraine says Russian troops not observing ceasefire
  • Heavy shelling hit Kharkiv and Sumy in the east overnight
  • Russian forces advancing on Mykolayiv in the south

Russia launched its attack in the early hours of 24 February from three main directions: north, south and east.

Since then, troops have poured into Ukraine and targets across the country have been struck by air strikes and artillery attacks.

The fight for Kyiv

Russian attempts to take Kyiv from the north have stalled in recent days after facing strong resistance from Ukrainian forces.

Heavy fighting to the north west of Kyiv around the key Hostomel airport continued on Friday.

The UK Ministry of Defence (MoD) says the front of a long convoy of Russian military vehicles remains in this area and has made little progress in recent days.

But aerial attacks on the city have continued.

To the east, however, Russian troops are now advancing rapidly on the capital, according to the Institute for the Study of War (ISW).

Defence analysts say the aim of the Russian forces is to envelop and eventually encircle the city.

Strike from the north

Chernihiv, to the north east of Kyiv, was the initial focus of Russian attempts to push south towards Kyiv.

The city has faced a barrage of aerial attacks, with several residential areas reduced to rubble, but it remains in Ukrainian hands at the moment.

The ISW says Russian forces have turned their attention to the city of Sumy in recent days, where locals have reported heavy shelling and a loss of power.

Russian troops initially made quick gains advancing from Belarus down the west side of the Dnieper river via Chernobyl.

However, the MoD says the main body of the large Russian column advancing on Kyiv remains over 30km (19 miles) from the centre of the city.

Strike from the east

Kharkiv, the second-largest city in Ukraine, has faced intense aerial bombardment in recent days.

Large residential areas in the city have been hit by heavy shelling, which UN prosecutors are now investigating as a possible war crime.

Russian paratroopers were reported to have been seen on the outskirts of the city but so far the Ukrainian military has kept hold of the city.

Analysts at ISW say the Russian forces appear to have decided against taking the city for now in favour of supporting other efforts in the region.

Shelling has also continued around Donetsk, which has come under attack from troops crossing from Belgorod in western Russia.

There are thought to be about 15,000 Russian-backed separatists in Donetsk and Luhansk, who may help a Russian advance. Ukraine believes the figure is higher.

Strike from the south

The most significant areas under Russian control at the moment are in the south of Ukraine.

Russian troops took control of Kherson, the first major city to fall, earlier in the week and several other cities have been surrounded.

A temporary ceasefire was announced on Saturday in Mariupol, which has been encircled for several days, and nearby Volnovakha.

The ceasefire was designed to allow civilians to leave the two cities for Zaporizhzhia to the west, along an agreed humanitarian corridor - but Ukraine has accused Russian troops of shelling areas along the route.

If the Russians take Mariupol, it would create a land bridge between Crimea and territory held by pro-Russian separatists in Donetsk and Luhansk.

Russian forces are also continuing to push north along the Dnieper river in an attempt to cut off supplies to Ukrainian forces in the east.

The Zaporizhzhia nuclear power plant, the largest in Europe, was also seized by Russian troops on Friday after an intense battle on the site.

In the south west, the MoD warns that Russians are also advancing on Mykolayiv, a large port city on the Black Sea.

Thousands flee across borders

Since the invasion began, more than 1.2 million people have fled Ukraine, according to the United Nations.

The European Union estimates that up to four million people may try to leave the country because of the Russian invasion.

Refugees are crossing the borders to neighbouring countries to the west, such as Poland, Romania, Slovakia, Hungary and Moldova.

About these maps

To indicate which parts of Ukraine are under control by Russian troops we are using daily assessments published by the Institute for the Study of War with the American Enterprise Institute's Critical Threats Project.

From 2 March this daily assessment differentiated between "Assessed Russian-controlled Ukrainian territory" and "Assessed Russian advances in Ukraine", the latter indicating areas where Russians are believed to have launched attacks from but which they do not control.

To show key areas where advances are taking place we are also using daily updates from the UK Ministry of Defence and BBC research. To show locations where there have been attacks or explosions we are using reports that have been verified by the BBC.

The situation in Ukraine is fast moving and it is likely there will be times when there have been changes not reflected in the maps.
