Something similar happened during the Algerian Civil War (in some ways a microcosm of this present horrendous macrocosm).
There was an explosion in the Casbah that killed many civilians living there. The French claimed an FLN ammunition dump had inadvertently exploded. Later it emerged that the pied noirs had planted a bomb.
Robert Fisk, who was present at the aftermath of the Sabra and Chatila massacre, and whose journalism, though it faltered towards the end, was very good at highlighting the utter hypocrisy on all sides in the Palestinian-Israeli conflict, rated Alistair Horne’s A Savage War of Peace (about the Algerian war of independence) as an extraordinary feat of historical writing.
Just thought the book was worth a mention for those who might not have heard of it. Gillo Pontecorvo’s movie is also outstanding*. I used to use scenes from it when teaching the concept of jihad to GCSE students of Islam.
*It’s the only one I know of that was produced by an unrepentant terrorist (Saadi Yacef) and in which he reprises his role as a bomb maker.
