evidence: Videos emerged early on Friday of apparent damage and casualties at the St. Porphyrios Orthodox Church in Gaza City; the region's oldest church that was reportedly serving as a shelter for hundreds of Palestinians displaced in Israel's 13-day-old military campaign. [...] The incident at St. Porphyrios comes shortly after this week's explosion at the al-Ahli Baptist Hospital in Gaza City. That strike set off a fierce information war, with Palestinian militants blaming the IDF, and the Israeli military releasing evidence it said showed the culprit was an errant Palestinian Islamic Jihad rocket. [...] The St. Porphyrios church has already been the subject of disinformation efforts during the latest Gaza conflagration. Last week, social media users falsely claimed that the structure had been destroyed in an Israeli airstrike.
