Two Medecins Sans Frontieres volunteers, who disappeared in Baghdad on 2 April, have been released after being detained by Iraqi authorities for nine days.
The volunteers were working as part of a six-person team helping Iraqi medical personnel at the al Kindi hospital in north-east Baghdad when they went missing.
Francois Calas, a 44-year-old head of mission from France, and Ibrahim Younis, a 31-year-old logistician from Sudan, were weakened by their ordeal but are both safe and well. They have been reunited with their colleagues in Baghdad.
Calas and Younis were able to phone the organisation's offices in Brussels and Paris briefly after their release.
All MSF activities in Iraq were suspended after the disappearance, but are now expected to resume.
"I imagine that Calas and Younis will be flying home rather than continuing with the operation, but it is not clear at this stage," said spokeswoman Petrana Nowill.
