Conflict and displacement also carry with them the less visible scars of grief and trauma - feelings difficult to manage in adults, and even harder to manage in children. While it's unimaginable to ignore the effects of the war, can there really be reasons for optimism and hope? A group of Syrian artists believe so.
The tragedy behind Iraj's story is shared by millions of Syrians displaced by the ongoing conflict. The numbers related to this crisis are so big, it can be hard to think of them as individual stories, specific families, unique faces... Each story we hear has one thing in common: explosive weapons are always part of their heart-breaking account.
I know there are good people, kind people, loving people out there. You're probably one of them. So please, I urge you, donate some money to help these helpless war victims. We should not have to rely on charity but our government has failed to do enough and the opposition has been too consumed with inter-party spatting to curtail the government's inaction.
If policymakers are serious about resolving the crisis in Calais, they need to take immediate steps to fix this broken system. It has become clear that no progress will be made until funds are invested in educating and empowering the camp's residents, rather than continuing to segregate and dehumanise them.
The next few days provide an opportunity to make the step change the UNHCR has prematurely hailed in the way governments, working together, could make life easier for refugees and reduce the strain on the countries currently bearing the brunt. This requires collective political will and individual leadership from the government heads gathered in New York, but, as things stand, the odds are this chance is going to be missed.
Education is essential to protecting children on the move. It improves girls and boys wellbeing, and ensures they have the skills and knowledge needed to help rebuild their societies after conflict. Education truly cannot wait, and we need action for all children out of school. This week, the world has that chance. Let's make sure we take it.
But as thousands gather to show solidarity again today, the reality is that progress has been far too slow. Political leaders here and abroad just aren't facing up to the scale of the international problem. Urgent action is needed. Faced with the biggest humanitarian crisis since the Second World War, Governments and nations across the globe have done far too little to help.
It was a woman I'd never met who finally swung it. As I lay on a plump mattress under a duck down duvet one night in late April, I thought about what she, Liz, had done with her day. While I'd been sitting on my backside, shuffling words around and working my way through a variety of nut-based snacks, she'd been putting out fires, breaking up knife fights and comforting dozens of bewildered children who know her as a second mum.
Just over a year ago you will have seen a photograph of the lifeless body of Alan Kurdi on an Aegean beach. It was said that the photograph "shook the world", but more than 3,000 more people have died, or are missing, in the Mediterranean this year alone. We, and our politicians, might disagree about many things but we should all agree that the senseless death of children - on any scale - is not something that we can ignore.
