The governor of the Red Sea State in Sudan announced a curfew in areas of Port Sudan city that witnessed tribal confrontations that resulted in 4 deaths and more than 30 injured, according to medical sources.

Governor Abdullah Shankari asked the security forces to use ammunition if necessary, as directed by the Public Prosecution Office.

"A curfew is imposed ... from five in the evening until six in the morning," the circular issued by the Red Sea State Security Committee said on Sunday.

He added, "A joint force was sent to the gathering place, accompanied by a public prosecutor, and it has the right to use sticks or tear gas to disperse the gatherings."

For its part, the Central Sudanese Doctors Committee said in a statement, "The events have so far left 4 deaths and approximately 35 different injuries, all with live ammunition."

The French Press Agency quoted a source who said he witnessed the events as saying that the clashes between the Bani Amer and the Nuba tribes took place during the return of demonstrators from Nuba from a protest movement against the new ruler.

The source added that the demonstrators "on their way back passed through the Dar Al-Naim neighborhood in which Al-Bunni Amer lives, and because of the clashes that occurred between the two parties previously, Al-Bunni Amer thought that this was an attack on their homes, so they clashed with the Nuba."

Last January, 9 people were killed in a clash between the two sides due to personal differences.

The two groups live in two of the poorest neighborhoods of Port Sudan, the second largest city in Sudan, which is the main port for the country's exports and imports on the Red Sea and lies a thousand kilometers east of the capital, Khartoum.

The Nuba is an African tribe whose origins lie in the South Kordofan region in the center of the country, and its members migrated to Port Sudan decades ago to work in the port. As for the Bani Amer, they are one of the Beja tribes groups, who are the indigenous people of eastern Sudan.
