Russian soldiers are nine miles from the city centre of Ukraine's capital Kyiv, a senior US defence official has said.

Satellite images of a military convoy near the capital show it has "largely dispersed and redeployed".
The convoy was last seen near Antonov Airport and its movement could signal a renewed push towards the city.
The images photos show what appear to be resupply trucks and rocket launchers snaking along a road in Berestyanka, north-west of Kyiv.
The firm that took the photos said parts of the convoy were in positions in surrounding towns.

Russian forces have moved about three miles closer to Kyiv in the past 24 hours, according to a senior US defence official, as offensives in western Ukraine suggested a new direction in the war.

After days of being stalled, Russia's military could be as close as nine miles (15km) from the city centre. As well as advancing on the northwest route into Kyiv, troops are approaching along two parallel lines east of the capital.

The city's mayor, Vitali Klitschko, said he believed it has enough vital supplies to last a couple of weeks as nearly two million people remain in the capital, while his brother Wladimir said some men and women who had fled with their families are returning to fight.

US intelligence suggests some Russian troops may have turned back to the northeastern city of Sumy, but is is not clear why.

Chernihiv, northeast of the capital, is now isolated but the Russian military has not moved past this city, with heavy fighting reported as Ukrainians fight back. Meanwhile, the besieged southern port city of Mariupol is encircled. ( Sources: BBC, SKY NEWS)
