Evidence

A search located the specific source of this claim: an IDF statement reported by The Times of Israel, which said that Mohammed Suleiman Byouk, described as a Hamas military-wing commander, was killed in a strike in Gaza. Per the outlet's reporting of the IDF's own statement, the military said Byouk had 'infiltrated Israel' during the October 7 attacks and had since been 'planting bombs targeting Israeli troops' and working to 'restore Hamas's capabilities,' which the IDF characterized as a violation of the ceasefire. This matches the wording of the claim closely and confirms it originates from an actual Israeli military (IDF) statement, accurately reported by a mainstream outlet. However, repeated attempts to find independent corroboration of the underlying allegations against Byouk (e.g., from Palestinian sources, human rights monitors, or dedicated fact-checking organizations such as Reuters Fact Check, AFP Fact Check, Bellingcat, or EUvsDisinfo) were blocked by a technical search-tool limitation reached during this session, so no independent verification or dispute of the substantive allegations (that he participated in October 7, planted bombs, or rebuilt Hamas capabilities) could be found or ruled out.
