While multiple sources confirm that five Palestinians were killed, the evidence indicates these deaths occurred across different incidents and locations (four in Nablus and one in Nabi Saleh), rather than as a single event tied specifically to the erection of four new outposts. The Al Jazeera cross-reference links the deaths to the outposts, but the detailed web search results describe raids and separate attacks (e.g., in Tell and Nabi Saleh), suggesting the claim oversimplifies or misrepresents the causal link and geography of the fatalities.
