Thanks to yerushalmi in the comments for the pointer to this wonderful 1956 vintage 14 minute film from the Spielberg archives on the dangers of life on the Gaza border: The Defenders. Kibbutz Kissufim is (was?) just north of Kibbutz Ein Hashlosha where the young Ecuadorian volunteer was just shot and killed and an Israeli TV crew came under attack. In fact, Ein Hashlosha is mentioned in the film.
