Another Russian helicopter shot up in S. Sudan
If you're a Brit forget the British Foreign Office reports on South Sudan, what you need are the reports from the US Embassy in Kampala as they are up to speed.
If you are going to Juba just make sure you are staying somewhere secure and that you are with a group of people. There are talks of Al Shabab operatives wanting to hi-jack expatriots in much the same way as is happening in Somalia.
Aside from the Islamic threat the local militia and the SPLA regular forces are totally unreliable and can do anything at any time. As I said there are more small arms fire incidents taking place than are being reported in the news.
If you go there you'll see!
