The UN's Under-Secretary-General for Humanitarian Affairs was chased from a refugee camp in the Darfur region by an angry mob

CNN:

The journalists and aid workers traveling with Jan Egeland, including CNN's Nic Robertson, were also forced to flee Monday.

After Egeland left, U.N. officials said an African Union peackeeper was killed.

The man was hacked to death when a civil police post was overrun after Egeland fled the camp. The man was serving as a translator for the police.

Egeland condemned the killing, saying it was the result of rising tensions in the camp. He urged local officials, UN officials and African Union leaders to find a way to calm the tensions.

According to Robertson, the crowd at the Kalma camp turned ugly when someone misinterpreted what an Oxfam interpreter was telling Oxfam officials and decided that he was a government spy.

The mob tried to stab the man and to pull him out of a U.N. vehicle, breaking windows in their efforts.

The vehicle, in which Robertson was riding, finally pulled away from the crowd. Video shot by CNN photographer Neil Bennett showed several refugees surrounding the vehicle, and angry shouts could be heard.

Egeland and his entourage also had to flee the demonstrators, who had earlier been demanding that U.N. peacekeepers come to the region.
