Want to share this article, We Pray for the Future on Huffington Post, written by a collegaue of an old friend who now teaches at the Anabaptist Mennonite Biblical Seminary. It is a good response to a very bad situation exploring some of the questions of the values of buildings and of national/political identity for Christians, especially as a minority. This should highlight that this is a complex situation, and like all significant conflicts, is not a simple two-party dispute.
The article links to a site with a thorough documentation of the attacks with attempts to verify. I've reposted some of the twitter photos of a few of the churches below. Note that these three are Coptic churches, but other Christians of any denomination were targeted.
