Anti-government protests that started on Wednesday in northern Sudan have been spreading to other cities, including the capital, Khartoum.

The protesters are angered by a proposed hike to bread and fuel prices, and have been calling for a change of government.

On Thursday, a university student was killed during clashes with security forces in a demonstration in the Sudanese city of al-Qadarif.

"The situation in al-Qadarif has become dangerous and the protests have developed to include fires and theft and it's now out of control," lawmaker Mubarak al-Nur told reporters.

Demonstrators in al-Qadarif and in Dongola, 310 miles (500 km) north of Khartoum, also set fire to the local headquarters of President Omar al-Bashir's National Congress Party.

Meanwhile, opposition movement Sudan Change Now has posted a video showing protesters passing through the streets of Khartoum.
