The group said Montserrat Serra and Blanca Thiebaut, who were abducted from the Dadaab refugee camp Oct. 13, 2011, have been released and will be returned to their families.
Doctors Without Borders said the women are healthy.
"As we are still working on the return of the two girls to their homes, we ask you to respect their need for privacy at this time," the group said. "MSF wishes to thank everyone involved in securing their safe release. Once again, MSF strongly condemns this attack on humanitarian workers who were in Dadaab offering lifesaving medical assistance to thousands of refugees."
