'Against Erasure': Gaza's photographers fight to be seen

"Art is my way of turning pain into hope." Those are the words of Gaza-based photographer Belal Khaled, whose images have been seen by millions and published in Time, the Guardian and The Wall Street Journal. His work, along with that of 10 other Gaza-based photographers, is at the heart of a powerful new exhibition at P21 Gallery in London, titled "Against Erasure: Photographs from Gaza." In a war where foreign reporters have been banned from Gaza, these photojournalists risk their lives to document what's happening and ensure their stories are not silenced.
