NEW YORK, JAN 28, (DNA) – Malala Yousafzai said on Friday that she was “heartbroken” by Donald Trump´s order on refugees and urged the US president not to abandon the world´s “most defenseless.”

“I am heartbroken that today President Trump is closing the door on children, mothers and fathers fleeing violence and war,” said the 19-year-old, shot in the head by the Taliban in 2012 after publicly advocating education for girls in her home country.

“In this time of uncertainty and unrest around the world, I ask President Trump not to turn his back on the world´s most defenseless children and families,” she added in a statement just moments after Trump signed the decree.

Yousafzai is the youngest ever recipient of the Nobel Peace Prize, which she shared in 2014 with India´s Kailash Satyarthi, a fellow education activist.

Now living in England, she made a remarkable recovery after undergoing medical treatment and has traveled the world as a campaigner.

“I am heartbroken that America is turning its back on a proud history of welcoming refugees and immigrants — the people who helped build your country, ready to work hard in exchange for a fair chance at a new life,” she said.

The decree signed by Trump was entitled: “Protection of the nation from foreign terrorist entry into the United States.”
