Stranded refugees launched a stinging tirade against the beleaguered German leader, saying she sold them a pack of lies during her infamous speech when she rolled out the red carpet to migrants from across the Middle East. Today they launched a desperate plea for her to be held accountable for the ongoing migrant chaos, telling Express.co.uk that they "risked their children's lives" on the back of her supposed warm welcome. Migrants who believed that they were being welcomed with open arms by Mrs Merkel have actually encountered barbed wire fences, riot police and increasingly hostile publics turning against them. One disconsolate refugee gave this website his personal message to the German chancellor, pleading: “Why couldn’t you say no from the beginning?” Express.co.uk visited four squalid camps in Serbia where migrants are living in filthy conditions whilst dreaming of a better life. Amongst their downtrodden ranks we found a growing backlash against under-fire Mrs Merkel, who many migrants now blame for their desperate plight.

The German chancellor publicly announced Syrians would be welcomed into her country with open arms last year, offering them the chance to escape war, in what is now seen as the greatest political blunder of her leadership. Millions heard her call and flocked towards the main EU bloc, but a crisis ensued when other nation states panicked. Internal borders across the Schengen free movement zone were hastily restored - often with barbed wire and troops - leaving thousands of people stranded in 'no man's land'. Tensions have since boiled over in the squalid camps, and clashes between police and frustrated migrants were reported along the route from Syria, through Greece and the Balkans. But while this was happening, Syrians were still selling their belongings to raise the cash to reach the promised land having been promised a new life in Germany. The journey - either across the Aegean sea from Turkey to Greece or the Mediterranean from Libya to Italy - costs thousands of pounds and is fraught with danger. Thousands of migrants have drowned after being packed onto rickety smugglers boats which have sunk at sea. And those who have reached Europe have faced a startlingly different reality to what they are expecting, prompting outright fury at the lies they feel they were peddled by Mrs Merkel.

You let us risk our lives and the lives of our children, for nothing Mohibar Njar

One such woman is Mohibar Njar, who travelled with her husband and sons from Syria after handing over $7,000 (£5,000) to people smugglers. Asked how she felt about the German chancellor, she told Express.co.uk: "You open the door and then you close the door, why do you do this? "You said come to Germany and Europe and we will help you. Now we are miserable You said come. Now you don’t want us and we are stranded. "Why couldn’t you say no from the beginning? "You let us risk our lives and the lives of our children, for nothing.” She told how she and her young family walked for days through mud and rain, kept warm only by the prospect of reaching Germany where they would be safe.

But now, stranded in a desolate Serbian migrant camp, she admits: “We would have stayed in Syria. "You can never know how scary it is to take the boat, knowing you might die. Coming from a war, where you might die. "Now you change your mind. Why not come here and tell us why?" Former hairdresser Mrs Njar said the feeling among migrants in the camp is that they are "not human". Her anger was echoed by another 26-year-old woman, who did not want to be named, who travelled alone to Europe with her four-year-old daughter. She said: "We were afraid the whole way. "Before we left we heard that a lot of people had died and there is danger along the whole way. "I didn’t know what would happen in the boat or in the forest or if the smugglers knew I was on my own if something would happen to me. "I have been here for two months and I have no idea what will happen to me. Where will I go? Nobody tells us clear information, nothing. "We had two life jackets from the smugglers but before we left they took them from us and they said there was not enough room in the boat and they can fit more people in if the take them. Addressing Mrs Merkel, she added: ”Why did we do this if you change what you say? We did this because you told us we can."

Express.co.uk also spoke to 27-year-old migrant Ahahamad Ahmad, who has managed to reach the promised land of Germany but is now desperately waiting to be reunited with his wife Samah. He told Express.co.uk that the pair were separated in Syria because of the war, and that she was forced to leave their homeland later than him. He said: "She is crying every day. I am here with residency and now she is stuck. "Nobody will even tell us what is going on. Are we not human? Do we not deserve any respect from anyone? "I am doing an integration course to integrate with German society and I want to work and have a good life here. "My wife just keeps crying, every day, her mind is so bad. She isn’t well." Their anger has been sparked by Germany’s growing reluctance to accept any more refugees or migrants, after it was inundated with 1.3 million people last year alone. Under intense pressure from her own party and the public Mrs Merkel has reversed her position on asylum, now saying the numbers must be controlled after integration problems and furious protests. On New Year's Eve over 100 women reported being sexually assaulted in Cologne and robbed by migrant men, while rapes were reported across the country, sparking the wave of angry protests. By this point, women and children from Syria had already left their homes and headed for the country, which is the number one destination of choice for migrants.
