"We've heard from medical sources in the city of Omdurman, which is the twin city of the capital

Khartoum, as well as the hospitals that there are multiple injured protesters who came in with gunshot wounds," she said.
"There are reports of other injuries due to tear gas canisters as well as due to Rapid Support Forces (RSF) running over protesters in several parts of Khartoum."
General Abdel Fattah al-Burhan, the head of the ruling Transitional Military Council (TMC), told reporters on Tuesday the killings in the North Kordofan city of El-Obeid were "unacceptable".
"What happened in El-Obeid is a regrettable and upsetting matter and the killing of peaceful citizens is unacceptable and rejected and a crime that requires immediate and deterrent accountability," he was quoted as saying by the official SUNA news agency.
Protesters accuse the RSF, headed by al-Burhan's deputy General Mohamed Hamdan Dagalo, of shooting dead the five teenagers.
"The repeated use of violence against a civilian population underscores just how important it is for the military council to engage in a serious reform of the security forces," Awol Allo, a lecturer in law at Keele University, told Al Jazeera.

"We are talking about a significant period of transition but at the same time there is a significant degree of continuity [...] it's very difficult to expect security forces to act differently now."
On Tuesday, the UN children's agency UNICEF called on Sudanese authorities "to investigate and hold all perpetrators of violence against children accountable".
"No child should be buried in their school uniform," the agency said, adding the students killed were aged between 15 and 17 years.
In Statement on Tuesday, the country's acting education minister, Mahy Aldin Algaali, announced the indefinite closure of schools across the country.
At least five protesters, including four high school students, have been shot dead after security forces broke up a student protest in the Sudanese city of El-Obeid, opposition groups have said.
The killings on Monday came a day before protest leaders and ruling generals are set to hold new talks on Sudan's transition following the removal of former leader, Omar al-Bashir.
Gunfire rang out as teenagers rallied against fuel and bread shortages in the capital of North Kordofan state, residents said, at a time of heightened tensions between opposition campaigners and military rulers that took power following Bashir's removal.
A key protest group, the Sudanese Professionals Association (SPA), said "live ammunition" had been used against a "rally of school students" in the central town of El-Obeid.
In a post on its Facebook page, it urged "all citizens and medics" to head to hospitals treating the wounded.
"We call on our people to take to the streets ... to denounce the Al-Obeid massacre, to demand the perpetrators be brought to justice," said the SPA, which had launched the initial protests.
Authorities announced a nighttime curfew in four Sudanese towns following the incident. There was no immediate statement from the ruling military council.
The acting governor of North Kordofan, Mohamed Khidr Mohamed Hamid, told Al-Arabiya TV there had been a "slight friction" between protesters and security forces. He said he could not confirm who opened fire and a committee would investigate.
Videos circulating on social media purported to show students protesting outside El-Obeid's main hospital against the killings and injuries.Al Jazeera's Hiba Morgan, reporting from neighbouring Addis Ababa in Ethiopia, said students took to the streets demanding justice and better living conditions shortly before the shooting took place.
"The opposition called for nationwide protests to condemn the violence," Morgan said. "They say they blame the ruling military council for the death of the protesters."
Morgan said the protesters and opposition have also demanded that the police protect them.
"They say the military council and the police should not be attacking protesters as they voice their anger and demand a civilian government," she said.
According to her, a transition agreement between the military and the civilian opposition has not yet been signed.
Sudan's state news agency SUNA said authorities in North Kordofan closed all schools across the state until further notice and described the events as "regrettable".
In Khartoum, a witness said dozens of protesters took to the streets in several neighbourhoods after hearing about the El-Obeid violence, Reuters News Agency reported.
