The Regional Director for International Committee of the Red Cross (ICRC), Mr Patrick Youssef says the agreement signed between warring parties in Sudan last week to protect civilians has “failed to silence the guns.
The deal was intended to allow safe passage for people leaving battle zones, protect relief workers and to prevent civilians being used as human shields.
Mr Youssef said allowing Khartoum airport to accept humanitarian aircraft to help Sudanese civilians would be an immense game-changer.
He said there were injured people in Darfur who had no access to hospitals and basic services.
Meanwhile, the charity, Save the Children, has warned that armed groups are occupying hospitals in Sudan and looting life-saving equipment.
The charity said earlier this week, eight persons who were on oxygen in a health facility in the capital Khartoum were driven out by militia fighters while three clinics for internally displaced people in the Darfur region were looted and emptied of supplies.
