After your advise, we got the following reply from a guy in the United Nations.
However, its good to note that the Eastern side of DRC has never been stable for some time, starting all the way from Uganda downwards to Burundi. In Dec last year we had to go with some good security escort when we were doing some work in the GOMA direction. Infact, areas where we have refugee camps are never safe because of various factors within those confinements.
When in Arusha, we will be in Masai Camp and will try and contact you.
