AKIPRESS.COM - Security forces have clashed with demonstrators in Sudan's capital, Khartoum, as anti-government protests take place across the country, BBC reports.

Riot police have used tear gas to try to break up the large rallies.

The umbrella group of doctors, engineers and teachers co-ordinating the protests says they have been held in at least 50 places around Sudan.

They began last month over the economy, but are now focused on removing President Omar al-Bashir from office.

Journalist Zeinab Mohammed Salih told the BBC that Thursday was the biggest day of protests in living memory.

Police reportedly used tear gas to control the crowds in several neighbourhoods in Khartoum.
