Information minister Nadia Al-Sakkaf said on Sunday Yemen needs $1 billion for relief operations in coming months.
On the sidelines of a meeting on the humanitarian situation in Yemen in Qatar's capital Doha, Al-Sakkaf said the situation is fast deteriorating as the country faces lacks of all services and supplies including medicines, water, food and electric power.
The number of Yemenis who are food insecure has increased because of recent violence, she said, while warning that if no fuels are supplied urgently, relief operations will be suspended.
Before violence broke out in recent months, the UN was warning that half of the Yemen's population, more than 12 million, were in dire need for aid and food insecure.
Al-Sakkaf is head of the high relief committee which was lately formed in Saudi Arabia to coordinate and ensure the delivery of aid to the violence-stricken cities.
Yemen has been facing acute fuel shortages for weeks. The fuel crisis has led to other crisis as hospitals, power plants and businesses have been forced to shut down. Also, transport means have been stopped.
The crisis was triggered by a blockade on the country's sea and air ports which was part of a military operation by Arab countries against the Houthi militants.
The blockade has completely affected imports and exports forcing oil and gas projects and the Aden refinery.
Moreover, the blockade forced Houthi militants to confiscate the country's fuel reserve for their war.
