A Red Cross employee has been killed and another injured in a gun attack by suspected Islamist militants in Mali, the aid organisation says.
Armed men opened fired on an aid vehicle as it travelled from Gao to Niamey in neighbouring Niger to pick up medical supplies.
The International Committee of the Red Cross (ICRC) said in a statement that it was "profoundly dismayed" by the killing.
Islamist militant group Mujao told AFP that it had carried out the attack. The nationality of the ICRC worker who was killed has not yet been released.
The injured worker was a member of the national Mali Red Cross and is in a stable condition in hospital.
The vehicle the pair were travelling in was clearly marked with the Red Cross emblem and was later burned.
