Wheelchairs, crutches, and children's books were among the essential items that Israel is deliberately blocking from entering Gaza, according to a firsthand account from former president of Ireland Mary Robinson during her visit to the Rafah crossing.

The former UN High Commissioner for Human Rights spoke passionately from the location which lies between Egypt and Gaza. She formed part of a delegation from The Elders, which was convened by Nelson Mandela in 2007 and advocates for peace across the world.
