Ukraine war: Russian forces now three miles closer to Kyiv after making 'advances' on the ground in past 24 hours, US says

Russian forces are now about three miles closer to Kyiv after making advances on the ground in the past 24 hours, a senior US defence official has said.

After days of being stalled, Russia's military could be as close as nine miles (15km) from the city centre.

According to the defence official, here is what has changed in the past 24 hours:

• Russian forces have advanced on the northwest route into Kyiv - near Hostamel Airport
• East of the capital, they are also advancing along two parallel lines
• Some troops may have turned back to Sumy, but it is not clear why
• Chernihiv is now isolated, but the Russian military has not moved past this city - with heavy fighting still reported, and Ukrainians fighting back

In other developments, the satellite image company Maxar says new images show that a large Russian convoy that was headed for Kyiv and near Antonov Airport has largely dispersed and redeployed.

Photographs suggest armoured units are now manoeuvring in and through surrounding towns close to this airport.

Separately, there have been reports of internet outages around the city of Kherson - and the US estimates that Russia has fired more than 775 missiles since the beginning of the invasion.
