The International Committee of the Red Cross (ICRC) says two of its local workers have been shot dead in Yemen.
It is believed a lone gunman opened fire on their vehicle as they travelled through the northern province of Amran.
Aid agencies have been trying to reach millions of people in Yemen, who lack basic supplies because of the conflict that has been raging there for months.
The killings come just over a week after gunmen raided the ICRC’s offices in the southern port city of Aden.
They held staff at gunpoint and demanded money, vehicles and other equipment.
The attack, one of at least 10 recent security breaches the ICRC has faced in Aden, prompted the organization to temporarily suspend its local aid operations.
