CAIRO — A few weeks before the fall of her hometown to Sudan’s paramilitary group, Nadra Mohamed Ahmed, seven months pregnant at the time, trekked for nearly 40 kilometers (25 miles) across unsafe roads, along with her two children, until she found safe transportation to a shelter across the country.

“By the time I arrived here, I had lost a lot of blood,” said Ahmed from her tent at the overcrowded displacement camp in the town of al-Dabbah in northern Sudan. “I was admitted to the ICU, where I spent a few days and had a blood transfusion.”

Ahmed arrived in the camp two months before el-Fasher in West Darfur was seized by the paramilitary Rapid Support Forces, or RSF, which have been battling Sudan’s army for more than two years. The U.N. population agency estimates over 2,000 women have fled the city to escape the harrowing fighting.

More than 140 pregnant women arrived at al-Dabbah camps since el-Fasher’s fall last month, said Tasneem Al-Amin from the Sudan Doctors Network, a group of medical professionals tracking the war. Many of these women arrive suffering severe complications, especially hemorrhaging, which sometimes culminate in a miscarriage, she told The Associated Press in a text message.

Last week, Anna Mutavati, the U.N. women’s regional director for East and Southern Africa, told reporters that Sudanese women are forced to give birth on the streets.

Last month, RSF forces rampaged through el-Fasher, following more than 500 days of siege. The paramilitary group had gone house to house, killing civilians and committing sexual assaults, according to relief agencies and witnesses.

The RSF also stormed the Saudi Maternity Hospital, the last functioning health facility in el-Fasher, reportedly killing 460 patients and their companions. The attack left more than 6,000 pregnant women with no access to life-saving maternal care, according to the U.N. The rampage has forced tens of thousands to flee their homes, embarking on a perilous journey, hoping to reach displacement camps.

Sami Aswad, U.N. population fund humanitarian coordinator in Darfur and North Sudan, said it is difficult to determine the exact number of pregnant women fleeing from el-Fasher, given the fluidity of the situation. However, the fund has estimated that more than 2,300 pregnant women must have left the city since Oct. 27, based on humanitarian tools used to calculate country-specific data in times of crisis, he told the AP in a video call.

On the ground, the UNFPA has so far facilitated a total of 102 deliveries, including natural birth and C-sections in both Tawila and al-Dabbah in recent weeks, he said. However, the newborns have to endure the difficult conditions at the overcrowded camps, he said.

Pregnant and lactating women are also enduring malnutrition in a country where food insecurity rates remain on the rise.

The rate of global acute malnutrition among the 66 pregnant or lactating women who were examined upon their arrival in Tawila by MSF between Oct. 27 and Nov. 3 was 60%, according to Tim Shenk, a communications officer with the international medical aid group.
