The office is located on a major street of the country's capital of Khartoum, and people from different areas of the city are currently gathering there.
The Sudanese army, on its part, cordoned off the main street of the country's capital Khartoum leading to the presidential palace, a Sputnik correspondent reported.
This follows confirmation from Sudanese Interior Ministry made earlier in the day that seven people were killed in weekend rallies in Sudan.
Later in the day, Sudanese Interior Minister Bushara Juma said that the country's law enforcement forces had detained almost 2,500 protesters during anti-governmental rallies in Khartoum on Saturday.
"Fifteen civilians and 42 law enforcement agents have been injured during protests. As many as 2,496 protesters have been detained in Khartoum," Juma said in his address to the country's parliament, as quoted by the Erem News website.
Rallies have been ongoing in Sudan since December. They were initially triggered by rising bread prices. Protesters, outraged with the tough economic situation, are calling for the resignation of President Omar Bashir who has been ruling the country for 30 years.
