From a story on axios.com by Dave Lawler headlined “Ukraine launches counteroffensive to retake Russian-occupied Kherson”:

Ukrainian forces have launched a much-anticipated counteroffensive in the south of the country, including around Kherson, a spokesperson for Ukraine’s southern military command announced on Monday.

Driving the news: The announcement followed reports of Ukrainian artillery strikes on Russian positions in Kherson Oblast, and unconfirmed claims from Ukrainian officials that Russia’s “first line of defense” near Kherson had been breached.

The latest: Two senior U.S. officials told CNN’s Jim Scuitto that Ukraine is targeting Russian weapons systems, command and control centers and ammunition depots in preparation for advances in southern Ukraine.
