Russia's forces sieged Izium nearly six months ago, and now the country has confirmed that all forces have now been pulled from the northeastern Ukrainian city. The new Ukrainian stronghold marks more rapid expansion into the northeast, a foray into the beginning of a new phase in the ongoing war.

Yesterday, Nextbigfuture had predicted that Ukraine would take Izium before the end of the month, but the Russian collapse has been more sudden than even I expected.

Institute for the study of War reports:
Ukrainian forces have captured an estimated 2,500 square kilometers in Kharkiv Oblast in the Kharkiv area counteroffensive as of September 9. Ukrainian President Volodymyr Zelensky and Ukrainian Commander-in-Chief Valery Zaluzhnyi stated on September 8 that Ukrainian forces liberated over 1,000 square kilometers between September 1-8 – a day before Ukrainian forces reached the southern approach to Kupyansk and the Oskil River on September 9. Ukrainian forces are likely clearing pockets of disorganized Russian forces caught in the rapid Ukrainian advance to Kupyansk, Izyum, and the Oskil River, given the influx of observed pictures of Russian prisoners of war in the past 48 hours.
