Ukraine says people can still only flee Mariupol by car or on foot

People are still only able to flee the besieged Ukrainian city of Mariupol on foot or by private car as efforts to organise mass evacuations by bus to safer parts of Ukraine have failed, Ukraine's Deputy Prime Minister Iryna Vereshchuk said.

Buses cannot reach the first part of the evacuation route from Mariupol, which is "nearly 80 km (50 miles)- people have to either walk or find a way to make this journey in a private car," she said on national television.
