The Kremlin on Wednesday said there was "no alternative" for Russia than to continue its offensive on Ukraine that it launched in 2022.

U.S. President Donald Trump blasted the United Nations and Europe on his return to the world body Tuesday, warning that migration is sending Western nations "to hell" and dismissing climate change as a "con job."

U.S. President Donald Trump relentlessly mocked the United Nations on Tuesday in his first address since his White House comeback, blasting it for failing to bring peace and claiming the world body encourages illegal migration.

Russia and Ukraine swapped accusations of deadly drone strikes on civilian areas of their countries Monday as Ukrainian President Volodymyr Zelenskyy anticipated "a very intense week" of diplomacy at the U.N. General Assembly in New York, where the Security Council was expected discuss the more than three-year war.
