The public health ministry in Yemen has appealed to the international community to intervene to help more than 700.000 diabetes patients as the country has completely ran out of insulin.
All basic services have been deteriorating amid the eight-month conflict and blockade on Yemen's sea, land and air ports.
The blockade was imposed by the Saudi-led coalition as part of the military operation launched in late March.
In its statement, the ministry urged immediate action to provide medicines primarily those being held in Djibouti due to the blockade.
Recently, international organizations said the healthcare system in Yemen was on the brink of collapse and warned of outbreaks.
Many hospitals have shut down because of lack of medicines, fuels and electric power.
According to the UN, around 14 million Yemenis are in need of urgent medical help and around 500.000 children are facing acute malnutrition.
In some provinces such as Taiz, raging battles have left the people face harsh conditions since there has been no supplies and no access to aid delivery.
