The Sana’a civil aviation authorities have prevented the arrival of humanitarian flights from entering and leaving the airport since December 19, Haq stated.
UNHAS is a pivotal link for humanitarian workers movement and delivery of supplies to Yemen, Haq stressed.
Earlier this week, a UN team visited the Sana’a airport to assess the damage caused by recent air strikes and noted that the facility could remain operational for emergency humanitarian use.
On December 20, multiple airstrikes hit at least six areas of the airport, according to press reports.
The UN special envoy for Yemen Hans Grundberg warned last week that Yemen is reeling towards a new war chapter “fragmented and bloody”, as the military escalation builds up.
According to United Nations data, Yemen is currently facing up one of the worst humanitarian crises in the world, largely due to the conflict between government troops and Houthi rebels.
