The U.S. military is preparing to place additional forces in Djibouti for a potential mission to evacuate U.S. Embassy personnel in Khartoum, Sudan's capital city, a senior U.S. official confirmed to Fox News. 

Embassy staff has been sheltering in place since Saturday, when gunfire and explosions erupted in the capital amid conflict between the paramilitary Rapid Support Forces (RSF) and Sudan's army. The two sides are battling for control of the country, with 5 million city residents and U.S. personnel caught in the crossfire. 

"The Department of Defense, through U.S. Africa Command, is monitoring the situation in Sudan and conducting prudent planning for various contingencies. As part of this, we are deploying additional capabilities nearby in the region for contingency purposes related to securing and potentially facilitating the departure of U.S. Embassy personnel from Sudan, if circumstances require it," Defense Department spokesman Lt. Col. Phillip Ventura said. 

"As a matter of policy and security, we do not speculate on potential future operations," he added.

Politico first reported plans to rescue embassy staff, who are sheltering just eight miles from Khartoum's international airport. The airport has been left inoperable by heavy fighting, and military evacuation appears to be the only way the 70 or so embassy staffers can escape Sudan without serious risk to their lives. 

According to Politico, Deputy Secretary of State Wendy Sherman met with lawmakers privately Wednesday and said that troops would be moving to Djibouti, where Camp Lemmonier is located, to give the Biden administration options to launch an evacuation operation. "Sherman stressed that the mission would whisk only embassy staff to safety and that there won’t be a military-led general evacuation of American citizens," Politico reported.  

"The Department of Defense, through U.S. Africa Command, is monitoring the situation in Sudan and conducting prudent planning," Ventura previously told Fox News. "The U.S. military maintains a constant state of readiness to support any number of missions around the world. As a matter of policy and security, we do not speculate on potential future operations or force movements." 

"Within Sudan, the Department of Defense’s mission is primarily focused on providing security at the U.S. Embassy," Ventura added. "While operational security prevents us from going into detail, the Department of Defense, through the Marine Corps Embassy Security Group, provides ongoing security for diplomatic facilities worldwide."

The White House made similar comments Wednesday and condemned the violence, which has claimed the lives of at least 270 people and left as many as 2,600 injured. The Sudanese Doctors' Union reported that nine hospitals have been damaged during the fighting and 16 have been evacuated. 

"The United States condemns in the strongest terms violence between the Sudanese Armed Forces…and the Rapid Support Forces," White House press secretary Karine Jean-Pierre said Wednesday, adding that the violence "recklessly" endangers Sudanese people.

Jean-Pierre encouraged Sudanese leaders to "engage in dialogue without delay" for the safety of their country.

An attempt at a ceasefire between the two armed forces failed on Wednesday. The 24-hour ceasefire was supposed to begin at 6 p.m., but eyewitnesses told Reuters that there was still fighting.

The conflict has disheartened hopes for democracy in Sudan after decades of dictatorships. Bombardments were reported in central Khartoum, the country's capital, as residents struggle with power outages and a dwindling food supply.
