Model Bella Hadid, 21, says she stands with Palestine, in a lengthy Instagram post she wrote on Thursday in response to President Donald Trump's decision to officially recognize Jerusalem as Israel's eternal capital.

Hadid also participated in a "Free Palestine" protest in front of the U.S. embassy in London.

"A very very sad day," Hadid wrote. "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." She continued, "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."

She continued, "The TREATMENT of the Palestinian people is unfair, one-sided and should not be tolerated," Hadid said in her Instagram post. "I stand with Palestine. There is no hatred against anyone… There are no sides… All religions living side by side." She concluded her rant by writing, "Where is the hope?"

Palestinians took to the streets and waged violence against Israelis, as they had promised with their announced "day of rage" in response to Trump's recognition of Jerusalem as Israel's capital. Palestinian protesters burned the Israeli flag, threw stones and fired rockets at Israelis. The Israelis Defense Forces responded with an airstrike.

Despite the anticipated violence from the Palestinians, Israeli security did not impose restrictions on Palestinians who wished to attend the Al Aqsa Mosque services on Friday evening.

This isn't Hadid's first time injecting herself into politics. In January, she and her sister Gigi protested in a march against President Trump's temporary visa ban.

Hadid also participated in a "Free Palestine" protest outside the U.S. embassy in London on Friday. "From the river to the sea, Palestine will be free!" and "Hands off Palestine!" the protesters shouted. She appeared to stay for a few moments before leaving with her security.

Hadid's father Mohamed told TMZ President Trump's recognition of Jerusalem as Israel's capital was "a sad day" in his life. Hadid is Palestinian. He was approached by TMZ outside of Il Pastaio, one of his favorite Beverly Hills restaurants, on Thursday week. The reporter asked him, "you were born in Israel," to which he replied, "I was born in Nazar — I was born in Palestine."

The reporter proceeded to ask him what he thinks about President Trump's decision to move Israel's de facto capital to Jerusalem. "Well, I think, for me, it's a sad day in my life," Hadid said. "There is no reason for this at this time. We are always hoping that we coexist together, co-live together, and have peace between Palestinians and Israelis."
