President Volodymyr Zelensky on Tuesday linked historic pro-democracy protests in Kyiv one decade ago to the invasion of Ukraine, describing the demonstrations on Maidan square as the "first victory" of the war with Russia.
Russia said on Tuesday it fended off Ukraine's attempts to get to the occupied eastern bank of the southern Kherson region, and claimed Kyiv's army had suffered "colossal losses".
US Defence Secretary Lloyd Austin made an unannounced visit to Ukraine on Monday, in a bid to stem Kyiv's concerns that support from its biggest ally could waver.

Ukraine's Marine Corp said Friday that their forces had carried out a series of attacks on the Russian-occupied east bank of the Dnipro river near the southern city of Kherson.
