War Escalates as Ukraine and Russia Exchange Attacks and POWs.

Pro-Ukrainian armed groups have launched cross-border attacks from Ukraine into southern Russia, taking Russian prisoners of war. The governor of the besieged Belgorod region has offered to negotiate with the armed groups to retrieve the prisoners. Russia has claimed to have repelled a "sabotage group of Ukrainian terrorists" seeking to cross the frontier near the settlement. The attacks on the Belgorod region come as Kyiv says it is preparing a major counteroffensive against Russian forces.
