I think the best intelligence gathering network in Nigeria is Miyetti Allah, the Fulbe cattle rearers association. With scores of thousands of Fulani cattle herders and their families moving all around the country as members of Miyetti Allah, these guys are the most reliable source of information on happenings in any area, no matter how remote for the news media it is..
Another advantage Miyetti Allah has is that its nomads usually can enter into places not even the Nigerian Army can. This is because Fulbe nomads are a close-knit society, you touch one and you have touched all. Thus usually no matter the issues the locals have with themselves, they usually leave the Fulbe and their cattle alone. Acting otherwise and attacking them usually unleashes an endless cycle of revenge with Fulbe nomads all the way from Darfur to Senegal mobilizing to come take revenge.
A good example is Jos. When the Hausa and the Beroms (backed by the Igbos) were busy killing themselves in the 2000s, the Fulani stayed aloof and neutral until some Berom who were Christian Evangelical fanatics attacked a Fulani settlement in Vom, Plateau State in November 2008 and killed over a hundred Fulbe women and kids. Then the Fulbe from all over, including places as diverse as Darfur and Guinea-Bissau began coming down to Plateau State, one clan or family at a time to carry out revenge attacks for that attack on their kin in Plateau State. Thus today the Fulanis who attack Berom villages in Plateau State are mostly those who just arrived in the state after migrating from such far away lands (Senegal, Darfur, Central Africa etc) to come avenge attacks by Berom on Fulbe settlements that occurred maybe 2-3 years ago (it takes time to trek on foot with cattle from Darfur). So normally you find nobody wants to mess with the Fulbe who when attack tend to keep taking revenge until they wipe out their enemy totally.
A second reason is that unless you want to stop eating beef, goat and ram, its advisable to not inconvenience or aggravate the Fulbe. They control the livestock trade in Nigeria because they are the only ones wiling to put up with the rigours of living a nomadic lifestyle..
So you find out that no matter the conflict, Fulbe nomads usually have access to areas otherwise closed off.
From what I know, Boko Haram has not attacked the Fulbe cattle-rearers and neither have they prevented them from migrating through routes inside insurgent-occupied territory. Apart from non-government employee/non-Christian indigenes of communities occupied by Boko Haram, Fulbe cattle rearers are the only ones who seem to be allowed to go in and out of occupied areas.
On another note, my next SITREP will be about the past failed advance by insurgent forces on Vimtim, Adamawa State.
I will also post a several part piece on Boko Haram organizational structure soon.
