Ukraine: Why has Russia’s 64km convoy near Kyiv stopped moving?

Russia’s huge military convoy, said to be 40 miles (64km) long, near Ukraine’s capital Kyiv has hardly moved in three days, the UK defence ministry says.

But US defence officials say Russia still intends to surround and seize the city where some three million people live – by siege tactics if necessary.

Recent satellite images showing the size of the convoy sparked fears that an attack would be imminent.
