Far-left extremists are reportedly planning to attack Alternative for Germany politicians during the AfD congress in Erfurt, with German security on high alert due to invitations to anti-fascist groups and the expectation of 50,000 counter-protesters.

Several claims have been evaluated regarding the AfD congress in Erfurt. The first claim about planned attacks by far-left extremists at the congress lacks concrete evidence. No direct sources confirm such plans, though police expect large protests. The second claim regarding the timing of the AfD’s federal congress in Erfurt is corroborated by multiple sources, confirming the congress is scheduled for July 4-5, 2026. The third claim about the invitation to international anti-fascist groups lacks substantial evidence, as does the claim about the number of expected counter-protesters. These have not been backed by reliable, detailed sources. Overall, while some claims about the event's details are validated, others remain speculative without solid corroboration.
