"Today, 1.8 million children under the age of five are facing acute malnutrition, and 400,000 are affected by severe acute malnutrition", Cappelaere said late in October 31. The United Nations estimates that if this continues 14 million people, half of Yemen's population, could be in a state of starvation as a result of the conflict.
While in Hodeida, the lifeline of the Houthi-controlled north, Cappelaere said he learned that families can't make it to the hospital because of constant fear of airstrikes and shelling or because they have no money to pay for transportation.
On Friday, the Saudi-led coalition claimed to have been responsible for an attack on Sanaa International Airport and an adjoining air base being used by Houthi insurgents.
"Unfortunately, Amal is not the only Yemeni child suffering that fate", he told a news conference in Amman, Jordan.
Since Saudi Arabia and its Gulf allies launched a bombing campaign to oust the Iran-backed Houthi rebels in the spring of 2015, the United Kingdom has sold an estimated €4.2bn worth of arms to Riyadh.
Saudi Arabia is leading an Arab military coalition that intervened in Yemen in March 2015 to support the government of President Abd-Rabbu Mansour Hadi after the Houthi rebels forced him into exile.
On Thursday, Yemen's internationally recognised government said it was ready to re-start peace talks with the Houthis after recent efforts to meet ended in failure.
And Hollywood star Angelina Jolie, a special envoy for the United Nations refugee agency (UNHCR), appealed for an immediate ceasefire.
"As an global community we have been shamefully slow to act to end the crisis in Yemen", she said in a statement during a trip to South Korea.
Without resolution to ongoing conflict, Yemen could face world's "worst famine" for decades, Antonio Guterres says.
"First, violence must stop everywhere - with an immediate halt around critical infrastructure and densely populated areas", Guterres said, echoing a similar ceasefire call issued by the United States earlier this week.
"The only way to enable refugees to return home, and to bring down the overall numbers worldwide, is to end conflicts themselves".
According to a new report by the Armed Conflict Location and Event Data Project (ACLED), a nonprofit conflict-research organization, the Saudi-led war has so far claimed the lives of around 56,000 Yemenis. Saudi Arabia's alleged human rights violations are not limited to that country but have expanded beyond its borders, since there is an endless war in Yemen.
After UN-backed peace talks collapsed in September, the coalition announced it was re-launching an assault on Hodeida.
