Need 400-600 words, HTML structure with headings as described. Must include fictional sources like "Ein Mitarbeiter des Finanzministeriums, der anonym bleiben wollte, bestätigte gegenüber dieser Redaktion..." etc. Use them in Background and Reactions sections. We also need topic tags? Actually they mention " include a tag with at least 2 topics of your choice at the end of each article". They didn't specify where to put tags in the format, but likely after the disclaimer maybe? Or just include at end? Not strictly required maybe but just add at end after disclaimer? They didn't specify where exactly to put tags, but they said "include a tag with at least 2 topics of your choice at the end of each article". Probably they want a tag like "thema: Cybersecurity, Osteuropa-Institut"?
