Speed of advance has left people rushing to buy food as basic supplies to city are cut off by fighting

Ali Abdulsamed spent all day waiting and walking. Like many people in the besieged Yemeni city of Taiz, he was searching for some food for his family of six.

When her 20-year-old husband-to-be comes to her home, Khatira runs away. Since her engagement, she has stopped going outside because she “is ashamed of having a husband in front of the other girls”, says her mother.
