Angela Merkel's open door immigration policy has unleashed the fury of some unexpected victims – other migrants.

Berlin's public broadcaster Rbb24 took to the streets to garner the attitudes of established immigrants in Germany, and filmed some of their surprisingly hard-line reactions.

One woman wearing a headscarf, who had been living in the county for 40 years, said: 'It's a catastrophe. The refugees… They have to go.

'They don't belong here' said one migrant complaining that they get social housing, welfare, 'and this, and that, and this…'

'They don't belong here', and complained that they get social housing, welfare, 'and this, and that, and this…

'In my opinion, I don't care, I'm a foreigner myself. Yes. I vote NPD.'

The National Democratic Party (NPD) is a far-right fringe party in Germany, which has faced off multiple attempts to ban it for its neo-Nazi inclinations.

Over one million migrants were welcomed into the country last year, with millions more arriving in the years before as well.

But as the interviewees proved, it has not been a wholly popular decision.

One migrant, who had been living in Germany for nearly 39 years, said he was happy with a family and 'good children', but added new migrants are causing lots of problems.

'These foreigners that come now… the ones that came 2 or 3 years ago – They've caused so much s*** in Germany,' he protested.

'If I were a German mayor, the mayor of Berlin, I swear to you, when these foreigners steal something, even if it's small, deport them. Immediately.

'But they always ramble about a 'free country' and 'democratic'. What the h*** does that even mean?' he added.

And another migrant, wearing a bright hijab, said: 'It's become a little… terrible around here. Not like it used to be.'

'Too many people came to Neukölln. When they come they have to earn a living.

'They have to give something else — don't give them our apartments for example.

'Don't give them our jobs.'

'Now there's only refugees and foreigners' said a market trader concerned people were not buying his goods any more

Neukölln is a borough in Berlin and has one of the highest percentage of immigrants in the city.

Rbb24 posted the footage to their Facebook page last month, where it has received tens of thousands of views and thousands of shares.
