Russian and Ukrainian forces fought for control of the port city of Mariupol on Sunday, local authorities said, while Ukrainian President Volodymyr Zelenskyy appealed to Israel for help in pushing back the Russian assault on his country.

In the latest in a series of appeals he has made for help from abroad, Zelenskyy addressed the Israeli parliament by video link and questioned Israel's reluctance to sell its Iron Dome missile defence system to Ukraine.
