Deutsche Welle: Hundreds of families in Yemen had been trapped in their homes by fierce fighting in the southern port city of Aden, according to Associated Press (AP).

The UN Office for the Coordination of Humanitarian Affairs (OCHA) also said the escalating conflict in the last month had “worsened an already large-scale humanitarian crisis in the impoverished Arab state.”

In its latest report on the Yemen crisis, OCHA said the upsurge in violence had further deepened the hardships faced by ordinary Yemenis, and that people were running short of essential supplies, including food and medicine.

The UN reported that the only lifeline was coming from volunteers making dangerous runs with supplies across Aden’s harbor in unsafe boats.
