Sudan protests 'echo Egypt unrest'

30 January 2011 Last updated at 21:44 GMT

There have been protests in Khartoum, with some people calling for President Omar al-Bashir to step down in what appears to be an echo of recent events in Tunisia and Egypt.

Activists said that dozens of people were arrested.

The unrest came on the day it was announced that some 99% of South Sudanese voted to secede from the north in region's recent independence referendum.
