Warning that Syria refugee crisis will continue unless aid is delivered
The refugee crisis engulfing Europe was caused by the international community's failure to donate enough aid after the outbreak of the war in Syria, a British charity chief has said.
Rob Williams, chief executive of War Child, also warned the flood of families fleeing will continue for another year unless the 11 billion US dollars (£7.7bn) pledged in aid by the international community arrives on the ground in the next three months.
He told the Press Association the failure to let refugees work, or to provide their children with school places, left families with little reason to stay in the region, driving them to make the perilous journey to Europe.
He said: "The question is was the movement of up to a million refugees towards Europe avoidable, and the answer is definitely yes.
"The problem is the aid effort has failed to do anything more than keep people alive.
"The recent conference in London got pledges from major donors of sufficient size that, if they all come through, will be enough money to provide a school place for every child who has had to leave their house and live in a refugee camp. Then we have a really good chance of recovering the lost generation.
"But unless the money does come through in the next two or three months, we are not just looking at this summer of refugees moving but next summer as well. It will be a further disaster."
And, stressing that he was talking in a purely personal capacity and not for the charity, Mr Williams suggested that leaving the European Union could hinder future aid efforts.
He said: "Personally I think that coordinating with donors is really, really crucial and the failure of the aid programme in Syria is a really good example of how, if donors don't agree a reasonable shared vision for what they are trying to do, then things will go badly wrong. And they have gone badly wrong in this Syrian crisis.
"The more distance we put between us and our colleagues and donor agencies in other countries in Europe, the more difficult it will be to really have a sensible aid response to the next crisis."
Tomorrow will mark the fifth anniversary of the outbreak of the war in Syria, which has seen hundreds of thousands of people killed, towns reduced to rubble and millions displaced.
The chaos tossed up fuelled the rise of Islamic State (IS) - also known as Isis or Daesh - which now imposes a brutal rule over large parts of Syria and Iraq.
War Child provides psychological support for thousands of "deeply traumatised" children who now live in refugee camps.
Mr Williams said children fleeing the war jump out of their skin at the slightest noise, are left mute and terrorised by nightmares.
But those who manage to escape IS-held territory have endured a different and particularly potent kind of horror.
"Isis has a special impact on children because they really do target them," he said.
"They target the girls for sexual exploitation and target the boys for detention and then to train them into the ranks of the militia. They know that what Isis is doing is particularly brutal.
"The Syrian civil war is dangerous, but Isis has this added dimension of something really, really horrible only one or two steps behind."
Girls are sold as sex slaves to IS fighters at weekly markets, while boys as young as eight are being enlisted by the jihadis and taught to wield Kalashnikovs.
And public executions and beatings of those who make the tiniest transgression are commonplace.
Mr Williams said: "I have been an aid worker since 1988, which includes the Rwandan genocide, and this is the biggest crisis I've ever seen - in terms of how many people need a fairly high level of assistance, and how much trauma is being laid down on a whole part of the Middle East.
"I think we have lost this generation, we have now got a massive deficit. We have got two million children who haven't been to school for five years. Now the challenge is not to avoid losing this generation, but to get them back."
