Ukraine's General Staff says the nation's forces made some gains on the border of the southern regions of Kherson and Mykolaiv and repelled multiple Russian attacks in the east. The General Staff's daily morning update Thursday said the Russians "lost control over several settlements" on the border of those regions. Ukrainian forces also repelled 11 attacks in the Donetsk and Luhansk regions, the update said. At the same time, fighting over the Azovstal steel plant in Mariupol continued, the General Staff said. The commander of the main defending force at the plant said the Russians have broken into the mill's compound, where limited evacuations of civilians took place over the weekend before being halted. Russian incursions had occurred for two days and "there are heavy, bloody battles," a Ukrainian military official said in a video Wednesday. Russia is trying to stop the flow of Western weapons into Ukraine by bombing railroad stations and other supply-line targets, Russian officials said.
