(CNN) Three people have been killed in open fighting amid long-standing tensions between Sudan’s military and paramilitary groups.
Clashes took place around the presidential palace and army headquarters in the capital Khartoum, witnesses said.
The paramilitary Rapid Support Force (RSF) claimed to be in control of the presidential palace and several airports.
The The group said it was retaliating against a surprise military attack on one of their bases.

“No one has been able to enter the army general command and all strategic bases are under control,” Abdel Fatah al-Burhan said in a statement.
Sudan’s military said it was fighting the RSF in Khartoum, accusing the group of a “treasonous plot” against the country.
The Sudanese doctors’ union reported at least three civilian deaths in the clashes.
Meanwhile, medical sources at a hospital in central Khartoum told CNN on Saturday afternoon that dozens of civilians and military personnel had been injured at the hospital in the past few hours.

United Nations Secretary-General Antonio Guterres strongly condemned the outbreak of fighting.

The US ambassador to Sudan said he was sheltering himself amid clashes in the capital.
“I arrived in Khartoum late last night and woke up to the deeply disturbing sounds of gunfire and fighting,” Ambassador John Godfrey said in a tweet.
Meanwhile, US Secretary of State Anthony Blinken said the situation in Khartoum was “fragile” when asked by a reporter for comment during a press conference in Vietnam.
“The main parties in Khartoum reached a very important framework agreement a few weeks ago on how to transition to a civilian government. There is real progress in trying to move that forward,” Blinken said on Saturday.
