NATO Welcomes Finland, Sweden Remains Undecided.

Finland will officially become the 31st member of NATO on Tuesday, marking the completion of a swift journey into the military alliance for the Nordic nation following Russia's invasion of Ukraine. The move drew a pledge from Moscow that it will beef up its forces in border regions. Meanwhile, Sweden's application for NATO membership is still on hold due to Turkey's accusations that Stockholm harbours members of what Ankara considers terrorist groups, a charge Sweden denies.
