The White House issued a statement saying that the USA welcomes the announcement that Sanaa International Airport was allowing the flow of humanitarian aid to the Yemeni people, adding, "We look forward to additional steps that will facilitate the unfettered flow of humanitarian and commercial goods from all ports of entry to the points of need".
The three-year civil war continues to rage in Yemen, where 10,000 have died and around 3 million people have been displaced.
The United Nations Security Council on November 9 called for the blockade to be lifted, warning that otherwise Yemen would face "the largest starvation the world has seen for decades". The brief opening of the blockade for humanitarian deliveries also meant opening the Sana'a airport in Yemen's capital city.
A second flight carried Russian diplomats, according to an airport official who spoke on condition of anonymity because he was not authorized to speak to the media.
The remarks came as Yemen's defenseless people have been under massive attacks by a coalition led by the Saudi regime for almost three years but Riyadh has reached none of its objectives in Yemen so far.
It was not clear if fuel imports, crucial for supplying clean water, would resume as part of the easing of the blockade, he said.
Unicef, the UN's children's fund, said its flight was carrying 15 tonnes, or 1.9 million doses, of vaccines for diphtheria, tetanus and other diseases.
The blockade is "severely hampering humanitarian operations, impeding humanitarians to provide much-needed assistance to millions of people who rely on it for their survival", Ben Lassoued said.
On November 6, Saudi Arabia imposed a blockade on Yemen as a response to a missile launch from its territory in a bid to prevent the transfer of military goods to the Houthis, as the kingdom accused Iran of supplying Yemeni rebels with short-range ballistic missiles.
The conflict in Yemen pits Houthi rebels and forces loyal to Yemen's ousted president against the internationally recognized government and its main backer, the Saudi-led coalition.
Spokesman Jens Laerke of the United Nations humanitarian aid coordination agency OCHA said that the agency has not yet received a response from the coalition on allowing ships loaded with wheat and Cholera treatments to arrive at Yemen ports. More than 2,200 people have died.More news: David Cassidy in critical condition with organ failure
