Sweden has received U.S. assurances that it would be supported while its application to join NATO is processed by the alliance's 30 member-states, Foreign Minister Ann Linde said in Washington on Wednesday.

"Naturally, I'm not going to go into any details, but I feel very sure that now we have an American assurance,"  Linde told Swedish TV after meeting U.S. Secretary of State Antony Blinken.
