Satellite images taken on Monday show a Russian military convoy north of Kyiv that stretches for about 40 miles (64km) in an area north-west of Kyiv. It is substantially longer than the 17 miles (27km) reported earlier in the day, according to the US company Maxar.
Maxar, which filed a series of satellite images on the Russian military buildup on the Ukraine border, also said additional ground forces deployments and ground attack helicopter units were seen in southern Belarus, less than 20 miles (32km) north of the Ukraine border.
