The Azov battalion was defending Mariupol together with other soldiers of the Ukraine Army. After being promised support foces to the defeat the Russians ni support was forthcoming so the soldiers nt part of the said Batallion tried to flee from Mariupol - but was found by the Russian Army and the refugees surrendered to he Russians.
The next story in the media was that the Russians have now taken the wounded at the steel mill in Mariupol to Russian hospitals for treatment. Since they are part of the Azov Battalion - that committed war crimes against citizens themselves - it is highly unlikely that they would be released after treatment. According to a report by a French medical assistant who went to the Ukraine and worked together with the Azov Battalion, the battalion soldiers got Russian Prisoners delivered to them and on arrival they shot each prisoner in the knee and ask them a questioon - Who is that officer? - and if the prisoner answered or not they then shot the prisoners in the Head. The said volunteer afte witnessing what was really happening and made a video of the incidents he saw left the Ukraine disgusted by what he saw.
Although the above were covered by the headlines there were few fact about the situation other than Zelenskyy now trying to get the rest of he Azov Battalion still at the steel mill out of Mariupol by negotiation - but the chance of the Russians agreeing on that is remote.
I am not sure the above is true - since it is widely reported (also on this site) that the Ukraine Army has defeated the Russians and they are fleeing from Ukraine, while the Mariupol situation indicates otherwise.
