By Kanishka Singh, Frank Jack Daniel and Angelo Amante WASHINGTON/KYIV/ROME (Reuters) -U.S. President Donald Trump said on Thursday the United States would supply weapons to Ukraine via NATO and that he would make a "major statement" on Russia on Monday.

The arrangement allows Ukraine to get weapons it needs in its war with Russia while providing a way for Europe to increase its defense spending as promised.

U.S. military and NATO officials are discussing a possible plan that could be unveiled in the coming days to provide Ukraine with much-needed aerial defense weapons.
