The hundreds and thousands of Syrians who are displaced are more vulnerable to exploitation than ever - and the US Attorney General is determined to draw attention to the consequences of not dealing with the Syrian conflict.

Loretta Lynch, the first African-American woman in her role, believes that the Syrian conflict is a "moment of reckoning" that will prove whether nations have the will to deal with a burgeoning crisis on their doorstep.

"I think it's a moment of reckoning for the world," she said, speaking to ITV News exclusively. "We do have the resources to handle this issue."

She added: "We do have the resources to deal, not only with the overall crisis in Syria, but with the resulting parallel issues of trafficking, and just restoring people to their lives."

Yet the US has its own brutal history - and shocking present - in slavery, a horror that has never been fully eradicated.

Current, very low estimates put the number of people trafficked within the US at a staggering 60,000, yet there were only 297 convictions for trafficking last year.

Mrs Lynch said that while enforcing the law is key and securing convictions is important, that ensuring authorities put victims first, and that there is a "safety net" for those who survive human trafficking.

She said many women are trafficked from Mexico, and that "being able to reunite mothers and their children has been one of the best things we've been able to do".

Discussing the possibility of building a wall to ensure that people are not trafficked across the border - something Republican presidential candidate Donald Trump has put forward - Mrs Lynch said: "I've always found it more helpful to reach out to various communities, and build bridges."
