Fr John Boyle has this post from Iraq concerning the appalling massacre, a word of caution though, there are some graphic descriptions and images. Godzdogz also has a blog post up, Remember... we have Family in Iraq! which I would also urge you to read if you haven't already. ACN has been reporting the persecutions too, see here , here, and here.
As well as our prayers, there is practical support we can offer. ACN also do very good Christmas cards, so if you haven't already bought yours, have a look at the online Aid To The Church In Need shop. You can also find gifts, like this icon and rosary made in the Holy Land.
