BBC OS producer Kristina Völk has been following the lives of several people in Gaza since the beginning of the Israel-Hamas war in October last year. They have been in contact with her via voice messages, text updates or chats whenever they are able. Kristina shares the experiences across a timeline of six months of four women: Batool, Sanabel, Aseel and Layan. Kristina guides us through the messages that give a sense of the resilience, fear, strength and despair experienced under the bombardments of war.
