JUBA, March 7 (Xinhua) -- The war in Sudan, which has shattered millions of lives and created the largest displacement crisis, risks triggering the world's largest hunger crisis, World Food Program (WFP) Executive Director Cindy McCain warned on Wednesday.

Over 25 million people across Sudan, South Sudan, and Chad are trapped in a spiral of deteriorating food security, said McCain, who just concluded a visit to South Sudan, where she met families fleeing violence and an escalating hunger emergency in Sudan.

"The consequences of inaction go far beyond a mother unable to feed her child and will shape the region for years to come," she said in a statement issued in Juba, the capital of South Sudan.

"Today, I am making an urgent plea for the fighting to stop, and that all humanitarian agencies must be allowed to do their life-saving work," McCain said.

She said 20 years ago, Darfur was the world's largest hunger crisis and the world rallied to respond. "But today, the people of Sudan have been forgotten. Millions of lives and the peace and stability of an entire region are at stake."

The WFP said it is unable to get sufficient emergency food assistance to desperate communities in Sudan who are trapped by fighting because of the relentless violence and interference by the warring parties.
