Warning: This story contains disturbing images. Although, not graphic. Several people on social media have said that we don’t need to see these pictures in order to be aware of the human cost that the refugee crisis is having. But others have commented that seeing such images can help bring home the horror of a crisis.

In a blog post he said, "Some smugglers are so organized they even give receipts for their criminal business, but they care little for the lives of those they transport and make fortunes from. Their brutality may be expected, but what is inexcusable is the indifference and obstacles placed in their path by Europe’s leaders." Documenting the journeys of Syrian refugees, he revealed that his notebooks are full of tragedy.

Others too shared the pictures with thought-provoking comments:

The photos after this link just reduced me to tears. We have a responsibility to see this not as an abstract problem https://t.co/pdH4oqToph
