It was definitely a question of security as the U.N. will always take very seriously the security of its staff.

We have been told that all but five Sudanese national NGO (non-governmental organization) workers have been released.

There is a heavy build-up of troops on both sides of the border. It has been quite bad in the last three weeks. I think there is some cause for concern.

The total number of people affected was 13 United Nations staff.

We are aware that some NGO (non-governmental organization) workers have been taken hostage within Kalma camp.

We have heard from some sources that the SLA left the town.

Some aid is not being delivered to those who need it, which is making people desperate and driving them into camps.
