Ukraine has set up a military administrative office in Russia's Kursk region, where its surprise incursion into Russian territory continues, according to its top military commander. Gen Oleksandr Syrsky said the office would "maintain law and order" and "meet the immediate needs" of the population in the area. In a video posted on social media, Gen Syrsky is seen telling a meeting chaired by Ukrainian President Volodymyr Zelensky that the office has been created "on the territories controlled by Ukraine". Russian Defence Minister Andrei Belousov has said Moscow will send reinforcements to "safeguard" the population in the region.
