HAJJAH/AL MAHRA, YEMEN — 

A two-month cease-fire has given aid groups a chance to step up aid to Yemen's hungry millions, but malnutrition ravaging children is projected to worsen if fighting returns or humanitarian funding does not pick up.

"The benefits of the first weeks of truce are already significant," said Erin Hutchinson, Yemen Director for the Norwegian Refugee Council.

The group has been able to give aid to 12,000 people in one district of Hajjah province that has not been reached for more than three years.

More than seven years of conflict in Yemen have devastated the economy, displaced millions and pushed food prices out of the reach of many. Spiking global grain and commodity prices are adding further strain.

"Tens of millions of people in Yemen are living hand-to-mouth," said Richard Ragan of the World Food Program (WFP), which is trying to feed half of Yemen's 30 million people in one of its largest ever programs.
