Iran security official appears to fire on crowd at cemetery

The article's central claims that an Iran security official appeared to fire on a crowd at a cemetery during a commemoration for those killed in protests are strongly corroborated by Verification Source 1 (knockout.chat). This source explicitly states that "Security forces opened fire... as Iranians held ceremonies marking 40 days since the January protest killings." The language used, particularly "brutal crackdown," introduces a moderate level of bias, but the factual basis of the event is well-supported.
