'Proud Muslim' Bella Hadid has branded President Trump's decision to recognize Jerusalem as Israel's capital as 'absurd, unfair and one-sided'.

The supermodel, 21, took to her Instagram page to condemn the 'unjust' announcement, writing that seeing the news made her 'cry for the many many generations of Palestine' and her own family.

Bella has deep ties with the nation; her father, real estate mogul Mohamed Hadid, 69, was born in Nazareth and lived in both Syria and Lebanon before immigrating to the US aged just 14.

Taking to her social media on Thursday morning, the Victoria's Secret Angel warned the move 'takes us five steps back, making it harder to live in a world of peace'.

She wrote: 'I've been waiting to put this into perfect words but I realized there is no perfect way to speak of something so unjust.

'A very very sad day. Watching the news and seeing the pain of the Palestinian people makes me cry for the many many generations of Palestine.

'Seeing the sadness of my father, cousins, and Palestinian family that are feeling for our Palestinian ancestors makes this even harder to write.

'Jerusalem is home of all religions. For this to happen, I feel, makes us take 5 steps back making it harder to live in a world of peace. The TREATMENT of the Palestinian people is unfair, one-sided and should not be tolerated. I stand with Palestine.'

Bella went on to quote her friend and 'Palestinian sisters', DJ duo Simi Haze: 'It is absurd that Palestine, a country where Muslims Christians and Jews lived side by side for centuries, has been fighting to be recognized since the inception of Israel in 1948, and to add insult to injury yesterday Trump 'decided' to recognize Palestine's capital of Jerusalem as the capital of Israel - as if it's his to give away.

'This is a violation of international law and a huge setback to any hope for peace. In his speech yesterday, he never once mentioned Palestine but referred to Israel and "the Palestinian people" as if Palestine never existed.

'Jerusalem is and always has been the capital of occupied Palestine. Declaring Jerusalem as Israels capital is a calculated move to make Palestinians lose hope of ever gaining statehood in their own country.'

Bella's father, Mohamed Hadid - a Los Angeles-based real estate mogul worth an estimated $200 million - declared it to be the 'saddest day of my life'.

He wrote on Instagram: 'The Saddest day of my life as an American Palestinian.. and to all the Palestinians that have endured the Israeli occupation of our fathers and great grandfathers Land.

'Now Mr president Trump with a simple signature gave with no return Our beloved holy land Jerusalem to the Israelis as their capital ... this is not a real estate deal .. what’s worse that all the Arab leaders sold us out .. no shame no heart no soul.

She said: 'He was always religious, and he always prayed with us. I am proud to be a Muslim.'

The Los Angeles-born supermodel and her sister Gigi, 22, also joined the No Ban No Wall march in New York after President Trump announced his immigration ban in January.

President Trump received widespread condemnation for his decision to recognize Jerusalem as Israel's capital.

Calling it an act of political courage, he said: 'Many presidents have said they want to do something, and they didn't do it.

'Whether it's through courage or they change their mind I can't tell you. But a lot of people have said we have to do something, and they didn't do it.'
