German spy agency says Iran is still buying missile parts inside Germany

Fact-check index: 58/100 — The core facts (Iran intensifying missile-tech procurement in Germany despite sanctions, Germany being Iran's top EU trading partner) are accurately sourced to Welt, but the article overstates the source by claiming the Verfassungsschutz explicitly 'ties' the procurement push to the trade relationship, when the source merely states both facts adjacently without an explicit causal link.

• Verfassungsschutz says Iran has intensified efforts to acquire missile/rocket technology in Germany despite existing sanctions — Directly matches source: 'Der Iran intensiviert laut Verfassungsschutz seine Bemühungen, in Deutschland Technik für Raketenprogramme zu beschaffen. Trotz der aktuellen Sanktionen...'
• Germany is Iran's largest/most important trading partner within the EU — Matches source: 'ist Deutschland wichtigster EU-Handelspartner des Regimes'
• The agency explicitly ties the intensified procurement push to Germany's trading-partner status — Source places the two facts in adjacent sentences but does not state the Verfassungsschutz asserts a causal/explanatory link between them; the article's framing of an explicit 'tie' is an inference, repeated twice as if confirmed
• Hypothesis that high trade volume helps hide restricted shipments / makes German suppliers useful to procurement networks — This is the article's own speculative framing, not stated or supported anywhere in the Welt source
• The report names no specific firms, components, or programs — Consistent with the brief source text, which indeed contains no such specifics
