The fiery comments came even as Saudi Arabia said on Monday that it will begin reopening airports and seaports in Yemen those in areas not controlled by the rebels after days of closing them over a rebel ballistic missile attack on Riyadh.
Muhrez said more importantly, humanitarian aid can not replace commercial shipments. Jamie McGoldrick is United Nations humanitarian coordinator in the country.
Saudi officials offered no justification for the attack, which added even further to United Nations concerns about the shortages across Yemen.
The Saudi-led coalition fighting in Yemen announced a suspension of border crossing via air, marine and land routes following a ballistic missile fired from Yemen targeting Saudi capital Riyadh on November 6.
The Saudi ambassador to the United Nations, Abdallah al-Mouallimi, said the coalition would allow ports in allied government-controlled territory to open-in Aden, the country's second largest city, for example-but all ports in the Houthi-Saleh controlled north-like Hodeida port and Sanaa airport-were to remain closed until the coalition decided sufficient steps had been taken to prevent weapons from entering the country. It calls on Saudi Arabia to not target school, hospitals or other targets on its no-strike list and to broadly improve targeting.
Saudi Arabia and its allies intervened in Yemen in March 2015 to push back the Houthi rebels who control the capital Sanaa, and restore the government of President Abedrabbo Mansour Hadi to power.
On Monday, the coalition said it would reopen ports in areas held by allied forces and loosen restrictions it had raised after the firing of the missile, which was intercepted near Riyadh's worldwide airport.
We heard [from the Saudis] that Aden and Mukalla ports are now open - but this is not enough.
He also said that the more the blockade tightens, the more the Houthis will develop their abilities to "respond to the assault of the enemy". The Hodeida port is held by rebels in Yemen.
Saudi Arabia and the US have accused Iran of supplying the ballistic missile used in that attack.
With the humanitarian situation getting much worse, it appears 2018 will be hard for Yemen as this historical land is plagued with war and disease for another year.
