Rival factions of Sudan’s military agreed to renew a three-day ceasefire, shortly before it was due to expire.
The extension – for another 72 hours – follows intensive diplomatic efforts by neighbouring countries, as well as the US, UK and UN.
But there are continuing reports of heavy fighting in the capital Khartoum.
The previous truce allowed thousands of people to attempt to flee to safety, while dozens of countries have tried to evacuate their citizens.
Almost two weeks of fighting between the army and a rival paramilitary group have left hundreds dead.
people really sticks in the gullet,” he told the BBC.
“Of course the lives of the thousands who need to evacuate are important, but what about the 45 million who are left?
“Sudan’s population has 15 million people in humanitarian need and I think part of our call today as the International Rescue Committee is to say let’s not fall into that trap of thinking that once thousands are evacuated the problem is solved.”
An army statement quoted by Reuters new agency said it had taken control of most of Sudan’s regions but “the situation is a bit complicated in some parts of the capital”.
It has not been possible for the BBC to verify the army’s claims.
Foreign nations, including the UK, have been urging their citizens to leave the country as soon as possible.
Speaking on Thursday evening, Ms Jean-Pierre urged Americans to depart within the next 24 hours.
Evacuations are continuing, but many foreigners are still stuck in Sudan. Some have struggled to get to the airstrip used for evacuations.
Local civilians are continuing to flee the capital, where there are problems with supplies of food, water and fuel.
The number of Sudanese fleeing the fighting in Darfur have outnumbered Chadian residents in the village of Koufroun on the other side of the border, the UN children’s charity says.
Chad would not be able to sustain the influx of refugees if the situation worsened in Sudan, Unicef’s Donaig Le Du told BBC Newsday.
The fighting broke out on 15 April as the result of a bitter power struggle between the regular army and RSF.
Army commander Gen Abdel Fattah al-Burhan and RSF chief Gen Mohamed Hamdan Dagalo, better known as Hemedti, disagree about the country’s proposed move to civilian rule, and in particular about the timeframe of the 100,000 strong RSF’s inclusion into the army.
Both factions fear losing power in Sudan because on both sides there are men who could end up at the International Criminal Court for war crimes committed in Darfur almost 20 years ago.
