Sudan’s paramilitary group, the Rapid Support Forces, has accused the army of launching airstrikes on the country’s old presidential palace in the capital, Khartoum.
Residents of the city reported heavy bombing of the area but the army has denied the RSF’s allegation.
The old Republican Palace is located along the Blue Nile River, near the current premises that were inaugurated in January 2015.
The two warring parties have been holding peace talks in Saudi Arabia but there is little sign of progress.
