Russia's war in Ukraine is about to enter a new phase, with most fighting shifting to a nearly 350 kilometre (217 mile) front stretching southwest from near Zaporizhzhia to Kherson, parallel to the Dnieper River, British military intelligence said on Saturday.
Russian forces are almost certainly amassing in the south of Ukraine, anticipating a counter-offensive or in preparation
for a possible assault, the UK's Ministry of Defence said on Twitter.
Long convoys of Russian military trucks, tanks, towed artillery and other weapons continue to move away from Ukraine's Donbas region and are headed southwest.
