The Kirishi oil refinery, one of Russia’s largest, shut its CDU-6 crude distillation unit after a Ukrainian drone attack and a fire during the night of October 4.

Ukrainian Defence Forces struck a number of enemy targets, including facilities on temporarily occupied Crimea.

State Border Guard Service officer and aerial reconnaissance specialist Yurii Kasianov called the SBGS's statements about the lack of results in the strike UAV company a lie.

President Volodymyr Zelenskyy said that since the beginning of Russia's full-scale invasion, Ukraine has increased the potential of its defence industry tenfold.

Power outages have been reported as a result of enemy attacks on energy facilities. Emergency power cuts are in effect in Shostka and the Chernihiv region. Energy facilities have been damaged in the Kharkiv region.

Yurii Kasianov, an officer of the State Border Guard Service of Ukraine, an aerial reconnaissance specialist, said that the command dismissed the officer who was acting as commander. The soldier has been held on the territory of the military unit since Saturday.

Ukrainians do not seem to take President Volodymyr Zelenskyy's statement that he is not going to run in the next presidential election at face value.

Two people were killed and another was injured as a result of enemy drone attacks in the Kharkiv region.

On the evening of Sunday, 5 October, Yurii Kasianov, an officer of the State Border Guard Service of Ukraine, an aerial reconnaissance specialist, came to Maidan with his family and supporters to protest against the disbandment of his effective unit. The soldier said that they had been waiting for President Volodymyr Zelenskyy for more than two hours, but he never came.

In the Nizhny Novgorod region, the Sverdlov plant, one of the largest explosives producers in Russia under international sanctions, was targeted by drones.
