A news article by Marcy Oster on the JTA news agency/wire service website dated December 24 stated, “The Palestinian village of Deir Yassin was the site of a massacre by Israeli troops in 1948.” The problem: while it is true that Arab and pro-Arab sources have for many years alleged there was a massacre in Deir Yassin — just as they later alleged many Israeli army massacres — there is no evidence that it actually happened.
There were many Arab civilian casualties in the battle of Deir Yassin, but this was because the Arab military forces there employed the time-honored tactic of using Arab residents as human shields. The Jewish forces at Deir Yassin were the pre-state Zionist militias the Irgun Zvai Leumi and LEHI (the Stern Group).
The Zionist militias left one exit from the village open and pleaded with the residents, through a bullhorn, to leave. Many did. But many others were forced to stay in their homes by Arab soldiers. As a result, civilians were killed in the inevitable house-to-house fighting that ensued.
As an aside, it is well worth noting that there were no “Israeli troops” at Deir Yassin as there was no State of Israel when the battle was fought. The Irgun and the Stern Group attacked Deir Yassin because it was where snipers were based who targeted Jewish civilians in western suburban Jerusalem neighborhoods and the British authorities were doing nothing to stop the snipers.
