State of Russian occupation Oct 4 after annexation



Slavyansk or Sloviansk

According to Wikipedia "Sloviansk was one of the focal points in the early stages of the 2014 pro-Russian conflict in Ukraine as it was the first city to be seized by Russia-backed military troops.[7][8] It was retaken by Ukrainian forces in July 2014...On 4 July 2022, The Guardian reported that, after the fall of the Luhansk oblast, Russian invasion troops would continue their invasion into the adjacent Donetsk oblast to attack the cities of Sloviansk and Bakhmut. In early September 2022, Ukraine began a major counteroffensive, regaining several settlements in the Kharkiv region. This relieved the pressure on Sloviansk with the fall of Lyman to Ukrainian forces on October 1st 2022."
