'Gaza has been described over the last 15 years as a large open-air prison, with an air, sea and land blockade choking 2.2 million people within 365 sq km. Most young people have never left Gaza. Today, this prison is becoming the graveyard of a population trapped between war, siege and deprivation.'
"The generations to come will know that we watched this human tragedy unfold over social media and news channels. We will not be able to say we did not know. History will ask why the world did not have the courage to act decisively and stop this hell on Earth."
Philippe Lazzarini is commissioner-general of UNRWA, the United Nations Relief and Works Agency for Palestine refugees
