Like a train wreck, I'm horrified but can't take my eyes off it. So one more post. Hopefully we can shift to Christmas in the Middle East tomorrow. Some Twitter activity from the early morning (4 or 5 am by now Cairo time) on attacks in Tahrir. CSF are Central Security Forces (Quwwat Amn al-Markazi) under the Interior Ministry, who seem to be taking the lead instead of Military Police today. Strong language warning in at least one case. Mix of Arabic and English posts.
