The blockade of Yemen refers to a sea, land and air blockade on Yemen which started with the positioning of Saudi Arabian warships in Yemeni waters in 2015 with the Saudi Arabian-led intervention in Yemen. In November 2017, after a Houthi missile heading towards King Khalid International Airport was intercepted,[1] the Saudi-led military coalition stated it would close all sea land and air ports to Yemen,[2] but shortly began reopening them after criticism from the United Nations and over 20 aid groups[3] and some humanitarian supplies were allowed into the country.[4] In March 2021, Saudi Arabia denied the blockade continued, however, UN authorized ships continued to be delayed by Saudi warships.[5]

The blockade has contributed to the current famine in Yemen, which the United Nations said may become the deadliest famine in decades.[6][7] The World Health Organization announced in 2017, that the number of suspected persons with cholera in Yemen reached approximately 500,000 people.[8][9] In 2018, Save the Children estimated that 85,000 children have died due to starvation in the three years prior.[10][11]
Effects and supply shortage

As a result of the blockade there is a desperate shortage of necessary supplies such as food, water and medical supplies, to the extent that children are at risk of disease due to lack of drinkable water.[16]

A limited number of aid ships can unload, and the bulk of commercial shipping, on which the desperately poor country depends, is being blocked, creating a state of emergency for Yemenis.[17][18] In spite of entreaties, Saudi Arabia has failed to pay out any of the $274 million it promised to invest into humanitarian relief.[19][20]

The UN estimated that by the end of 2021, the conflict in Yemen had claimed more than 377,000 lives, with 60% of them died due to issues associated with the conflict, such as starvation and preventable diseases.[21][22] In March 2022, more than 17 million people in Yemen were experiencing high levels of acute food insecurity.[23]
