Reuters has a quick snap that Russian defence minister, Sergei Shoigu, has instructed the military to prioritise destroying Ukraine's long-range missile and artillery weapons, according to a defence ministry statement.

The UK's Ministry of Defence has claimed that Russia is using the private military company Wagner in Ukraine to reinforce its frontline forces, but that losses they have sustained are likely to be impacting their effectiveness.

Russia has used private military company Wagner to reinforce front-line forces and to mitigate manning shortfalls and casualties.

Wagner has almost certainly played a central role in recent fighting, including the capture of Popasna and Lysyschansk. This fighting has inflicted heavy casualties on the group.
