Putin Alaska summit while European Commission and NATO leaders emphasize any deal must protect Ukraine's long-term security interests.

BRUSSELS (AP) — Ukraine and its backers in Europe insist that the United States and Russia cannot decide on land swaps behind their backs at a summit this week, but the Europeans concede that Moscow is unlikely to give up control of Ukrainian land it holds.

European leaders said any diplomatic solution must protect their and Ukraine's interests. Zelenskiy said any decisions taken without Ukraine will be "stillborn."
