It is nearly two weeks since Israel launched its ground offensive into Gaza and more than a month since it began intensive air strikes against Hamas, following the brutal attacks in Israel in which more than 1,400 people were killed. ActionAid is one of the many charities responding to the humanitarian crisis in Gaza, and its UK CEO Halima Begum is urging countries that finding a humanitarian solution is paramount, with thousands of civilians dead and the majority of Gaza's 2.3 million residents having been displaced. Today on Ways to Change the World, Halima Begum tells Krishnan Guru-Murthy about her journey from youth activism to NGO work, the West’s ‘moral responsibility’ to humanitarian aid and the need for an immediate ceasefire in the Israel-Palestine war.
