Sudanese police have responded to small anti-government protestors in North Sudan with tear gas as protesters made a second attempt to overthrow the government, according to a report by Reuters.

In a move intended to emulate uprisings in Libya and Egypt, protesters voiced concerns about rising inflation and political uncertainty as the oil-producing south voted to secede ending decades of civil war.

The referendum held in January saw Sudan’s southern voters vote overwhelmingly in favour of separating from the less-populated north.
