Sudan's capital Khartoum continued to echo with sounds of gunshots and shelling on Saturday even after warring factions announced a three-day truce. Some nations have been evacuating their citizens from the war-torn African country.

The ceasefire between the Sudanese military and the Rapid Support Forces paramilitary group declared on Friday had yet to fully take hold as of Saturday. Friday was a Muslim holiday marking the end of the holy month of Ramadan.

The World Health Organization said that the fighting had left more than 400 people dead and over 3,500 injured as of Friday.

The ongoing conflict has forced at least 20 hospitals in the capital to close. The United Nations Population Fund estimates that nearly 220,000 pregnant women have been unable to receive proper care.

US President Joe Biden said his country's military conducted an operation to evacuate US government personnel from Khartoum.

The airport in the capital has repeatedly become a target of violence. Saudi Arabia said 150 of its citizens and people of other nationalities were taken by vehicles to Port Sudan, where they boarded ships that arrived in Jeddah on Saturday.
