Donald Trump has been left humiliated after a major NATO leader launched a furious swipe at America's plan during the war with Iran.

German Chancellor Friedrich Merz claimed the US "obviously went into this war without any strategy". He said during a discussion with students at a high school in Marsberg in the Sauerland region: "Especially since the Iranians obviously negotiate very skillfully - or do not negotiate very skillfully. An entire nation is being humiliated by the Iranian leadership."

During the discussion, Mr Merz also said: "Because the Iranians are obviously stronger than previously thought, and the Americans clearly lack a truly convincing strategy in the negotiations."
