WARSAW - Poland’s President has given the first address Sunday in person by a foreign leader to the Ukrainian parliament since the Russian invasion began. Andrzej Duda received a standing ovation after he declared that only Ukrainians themselves could decide their future. Earlier, the Ukrainian government said Kyiv would not agree a ceasefire deal with Moscow that involved giving away any territory. Presidential adviser Mykhailo Podolyak, said making concessions would result in Moscow starting an even larger, more bloody offensive in the longer term. Russian forces have continued their attacks on the eastern Donbas region following their capture of Mariupol. They are said to have made limited advances towards Severodonetsk, where it is thought they are planning a new siege.
