Yemen's war has left 15.9 million people, 53 percent of the population, facing "severe acute food insecurity" and famine was a danger if immediate action was not taken, Reuters reported referring to UN report.

The report was published when the UN gathered the parties to the conflict for peace talks, as it took place for the first time in two years after the war had been broken out. Humanitarian groups say peace is the only way of ending the world’s largest humanitarian crisis, the source noted.

While war was the main cause of the hunger crisis, it was aggravated by extremely high food prices, a liquidity crisis, disrupted livelihoods, and high levels of unemployment, the report said, adding food aid was not enough to bridge the gap.

The investigation has been carried out by Yemen authorities and international experts of IPC international system.

According to the report, several provinces of Yemen, with almost one million people’s population, face crisis and are deprived of humanitarian aid. At the same time, 13 provinces are on the verge of a humanitarian catastrophe.
