A document compiled within the IDF’s Gaza Division less than three weeks before October 7 warned that Hamas was training for a large-scale invasion of Israel during which hostages would be taken en masse, the Kan public broadcaster revealed Monday.

Titled “Detailed raid training from end to end,” the document was circulated on Sept. 19 and was reportedly brought to the attention of at least some senior intelligence officials, but apparently ignored. Kan did not specify who produced the document or clarify who may have seen it.
