'Armoured personnel carriers and support vehicles cross the border, while the 280-truck convoy comes to a halt separately

The white trucks of humanitarian aid rumbled through Russia in a convoy stretching for miles, moving slowly southwards on the M4 highway, amid a landscape of fertile fields and Ladas stopped at the roadside their boots overflowing with watermelons for sale.

But, while the trucks came to a halt well short of Ukraine's border, a different Russian convoy did make the crossing into Ukrainian territory late on Thursday evening.

The Guardian saw a column of 23 armoured personnel carriers, supported by fuel trucks and other logistics vehicles with official Russian military plates, travelling towards the border near the Russian town of Donetsk about 200km away from Donetsk, Ukraine.'
