The latest draft NATO summit declaration says the alliance will continue to support Ukraine "on its irreversible path to full Euro-Atlantic integration, including NATO membership," an alliance source told Reuters on Wednesday.

The draft, which has yet to be agreed by the 32 allies, confirms that NATO will be in a position to extend an invitation to Ukraine to join the alliance when the allies agree and conditions are met, the source said.

Latest NATO summit is taking place in Washington these days.
