Sudanese military forces recaptured the presidential palace early Friday in the battle-scarred capital, Khartoum, signaling a potential turning point in Sudan’s devastating civil war, now approaching its third year.

Soldiers posted triumphant selfie videos at the entrance of the devastated palace, which overlooks the Nile River, after days of heavy fighting with the Rapid Support Forces, or R.S.F., the powerful paramilitary group that the army is battling for control of Sudan.

“We’re inside!” shouted an unidentified officer as cheering soldiers swarmed around him in one video posted Friday morning. “We’re in the Republican Palace!”

Still, the R.S.F. fought back for the rest of the day on Friday, firing missiles from armed drones that hovered over the palace compound, Sudanese military officials said. One of them struck a crew from Sudan’s state television station, killing two journalists and a driver.

Two officers from the military’s media wing, including its top official in Khartoum, were also killed in the attack outside the palace.
