Yes. A few of the difficulties that happen with, for instance, NGO workers are that now they've changed the visa requirements so that any NGO worker within South Sudan has to go back for a visa. You're only allowed to stay a month and you're constantly flying back and forth between Juba and Nairobi, so they make it very difficult to stay.
Regarding humanitarian access, when Operation Lifeline Sudan and UNICEF used to fly, they used to fly all of their Hercules from Loki, and there used to be 20 Hercules a day that would fly over South Sudan and drop food. That doesn't exist now. You basically take the food in via road from Uganda, or from Kenya, or from wherever, so what tends to happen is that these UN convoys are attacked. Also when you talk about particular checkpoints, depending on where you're driving, you may actually hit different checkpoints that now have different requirements, so it changes all the time.
The South Sudanese government has changed requirements for years, so all of a sudden what you thought was happening a month ago isn't necessarily happening anymore. It is very difficult.
Does that help?
