Millions of Yemenis are edging closer to famine and fatal disease one year since the Saudi-led Coalition imposed a blockade on sea, land and air routes, an international NGO has warned.

The one-year-long partial blockade has prevented import of vital food, fuel and medical supplies, creating shortages on key commodities for a population in dire need. This had led to mass inflation and propelled a crisis already widely regarded as the worst in the world, the Norwegian Refugee Council said.

The parties to the conflict have consistently disavowed the laws of war and employed tactics that exacerbate suffering

“The past 12 months have been a never-ending nightmare for Yemeni civilians. The parties to the conflict have consistently disavowed the laws of war and employed tactics that exacerbate suffering for civilian populations,” said Jan Egeland, Secretary General of the NRC.

Fuel imports through Hodeidah, Yemen's most important sea port, remain drastically low and insufficient for meeting needs. The past days have also seen fierce fighting and air strikes pick up in the vicinity of Hodeidah city threatening to further deteriorate civilians’ access to safety and aid.

Twelve million people are left at imminent risk of descending into famine while over one million cholera suspected cases have been identified in Yemen. Over 22 million people need some form of aid or protection across the country.

"We call on parties to this brutal conflict, the UN Security Council and individual member states to take immediate steps towards a ceasefire, the full opening of all of Yemen’s ports, the restoration of public services and stabilisation of the Yemeni economy in the interest of arresting an entirely man-made humanitarian catastrophe," Egeland said.
