On Thursday, Sudanese police fired tear gas to disperse hundreds of protesters in the center of the capital, Khartoum, who were calling for the restructuring of the security services and the return of army officers to service after their retirement.

He called the demonstration "a gathering of professionals" who had led the protests against the regime of ousted President Omar al-Bashir for months, prompting the army to topple him in April.

A few days ago, the army issued a list of officers of various ranks, who were referred to retirement. The army spokesman, Colonel Amer Muhammad Al-Hassan, said, according to the official Sudanese News Agency (SUNA), that "pension statements and promotions" were issued "as is customary at the beginning of each new year."

However, as a result, a campaign spread on social media, denouncing the referral of the officer, Lieutenant Muhammad al-Siddiq, who protesters said was among those who defended and supported them at the start of their sit-in.

Hundreds of young protesters gathered close to the presidential palace carrying the flags of Sudan and banners reading "The army, the army of Sudan", "No to drive away the free army." The protesters burned old tires and blocked roads using stones.

Then the riot police who fired tear gas arrived and dispersed them.
