On the fifth anniversary of the Syrian revolution, George and Amal Clooney have drawn on their migrant roots in discussing the mass crisis after hearing the testimonies of several Syrian migrants.

George Clooney reflected on the difficulties faced by his family when they first arrived in America after moving from Ireland, calling on America to remember its migrant roots.

'It is what our country is, it is a country of immigrants. We have not recently done a very good job of remembering who we are,' he poignantly said at the meeting in Germany, organised last month byInternational Rescue Committee and led by its president David Miliband.

Human rights lawyer Amal Clooney also spoke of her own family's experience of fleeing Lebanon during the civil war and arriving into Europe in 1982 and her hopes for a free Syria.

George Clooney also reflected on the difficulties faced by his family when they first arrived in America after migrating from Ireland, calling on America to remember its migrant roots.

'My own family is from Lebanon ... they also ran away from a war and was lucky enough to be expected by a European country in 1982 when the violence there was really bad,' she told the Syrian refugees.

'I hope you will be able to go back to a safe and free Syria,' the human rights lawyer said.

George Clooney reflected on his family's Irish heritage and called for America to think of its roots.

His ancestor, Nicholas Clooney, was forced out of his home in Windgap, County Kilkenny, in 1853, in the wake of the potato famine, and that year moved along with his siblings to Kentucky, research reported in the Sunday Independent of Ireland has found.

However Clooney highlighted the difficulties Irish arrivals found in integrating into American life in the 19th century as he spoke

'My family were treated terribly and were not accepted and America learned to accept all these idea.'

'Being here talking with you is important to remind them of who we are and who we have always been which is you,' he said.

'You forget that these are people who didn't just leave their country for no reason at all. These are people who left because a terrible tragedy,' the actor said.

'We always look around at the end of these tragedies and say if we knew, we would have done something and the reality is, of course we know,' Mr Clooney said in the video.

'What is shocking to me is not that it happened but its continuing to happen for five years.'

'It's actually easy to dismiss giant numbers but it's very hard to dismiss a young child sitting on the ground crying as her mother said, 'If we die. I rather we die by a bullet because it would be quicker,'' Clooney said while meeting with refugees.

International Rescue Committee's powerful video features the Clooneys and International Rescue Committee president David Miliband as they hear the stories of Syrians in Germany.

The mother, who was one of three Syrian families the couple met, also told them the reasons she felt she needed to uproot her family and move to Germany.

She described the daily battle to survive the bombings and snipers before it became too much and they were forced to flee the country.

The Clooneys met another Syrian man, who described how he was locked up and tortured by the Assad regime.

Speaking after the meeting, Mr Clooney said: 'It was an honour to meet three Syrian families whose lives have been shattered by war and inspiring to learn that the people of Germany are helping them put their lives back together.'

The Hollywood star said he would also meet a group of asylum seekers 'to talk about and ask what messages and what things we can do... to help'
