I don't have any expertise in regard to the situation in Congo, and the information I have I snapped up in my general studies of the role of radical Islam across the world. That said, the descriptions on websites like
this one are rather worrisome. I'd be eager to hear about your views on the matter.
Not to put to fine a point on it, but I wouldn't call that site an example of journalistic integrity or quality -even by the low standards associated with internet blogs.
For example, in the first article on the linked to page, it discusses killings in the north-eastern part of the DRC (while, strangely, coloring in the Republic of Congo on the map) which are sadly common as a lingering remnant of the Congo Wars. Nowhere in the actual article from Reuter's does it the killings were done because of religion - indeed, the article mentions how they were only suspected to belong to the ADF and how the attackers were wearing DRC uniforms.
Nothing about that attack as reported makes it sound any different than the other killings and brutality that occur in the Kivus that aren't related to religion.
Additionally, the second article gave us this gem:
The goal is creating a big African-Islamic continent. Christians must be killed or expelled.
I mean, the authors somehow jump from unnamed groups in Nigeria issuing an out of context statement about kicking Christians out to somehow believing their is a grand Muslim conspiracy about conquering Africa.
It ends on an equally absurd note:
A prophecy which seems about to become true. Will the world stand to prevent another Rwanda?
This sort of statement betrays a deep lack of understanding of the Rwandan genocide, as religion was simply put not a meaningful factor in the genocide. The country was largely Christian, majority Catholic.
Although religious identities did not separate perpetrators from victims in Rwanda, my research indicates that religion was nevertheless an essential element in the Rwandan genocide. Contrary to the claims of some church authorities,(6) the involvement of the churches went beyond a simple failure to act in the face of atrocities or the individual transgressions of church members. As I will attempt to demonstrate in this paper, the culpability of the churches lies not only in their historic role in teaching obedience to state authority and in constructing ethnic identities but also in their modern role as centers of social, political, and economic power, allied with the state, actively practicing ethnic discrimination, and working to preserve the status quo.

Not to sound patronizing, but I would generally be quite suspect of articles that say things like "80 Christians killed by Muslims" and leave it at that. Unless somehow the article can show it is probably the killings occurred because of religion, it would be like reporting the Invasion of Iraq as "Christian bombers killed 80 Muslims in bombing raid" which I think we can all agree is a simplistic and misleading description of the conflict.
For lack of a better word 'tribal'* conflicts in some parts of Africa aren't uncommon and have been going back to the middle of the Cold War. The Islamic spin some put on can often be thought of as 're-branding' and not some expression of a desire for a global Islamic caliphate. Even amongst legitimately Islamist groups, desire for an Islamic caliphate is rare at best. Look at the Iranian Revolution: it was an explicitly Islamist affair but at the same time was also staunchly republican and nationalist without any sort of desire for a Caliphate.
*Calling African conflicts 'tribal' in my opinion is just laziness given how complicated the ethnic situation is. For example, in the lead up to the Congo Crisis of '61 and the Katangese secession, the Katangese-Baluba was concerned about Kasai-Baluba gaining influence inside Katanga and had quite different cultural backgrounds. To that end the Katangese-Baluba sided with the Lunda in Katanga against their 'brethren' from Kasai. (Ultimately, the Lunda and the
Union Katangaisekicked out the Katangese-Baluba and embarked on massacres against them.)
