The United Nations's new top human rights official is calling the Trump administration's family separation policy "unconscionable."

Michelle Bachelet in her first speech on Monday denounced the practice as a human rights violation.

She also told the U.N. Human Rights Council that there has been a lack of “redress” for migrant families separated at the southern U.S. border, The Associated Press reported, a policy that President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE discontinued under immense national pressure.

Bachelete, a former Chilean president, also called out Trump for seeking to indefinitely jail migrant children with their families, a policy that would overturn the ban on detaining children for more than 20 days, Reuters reported.

As of August, there were still more than 500 children who were separated from their families at the border that remained in U.S. custody, despite a July 26 deadline set by a federal judge for the reunification of all separated families.

Trump's "zero-tolerance" immigration policy, which resulted in the separations, drew national outrage over the summer when reports emerged that more than 2,000 children had been taken away from their parents. The president signed an executive order ending the practice, but migrant families have sued the Trump administration over the emotional trauma the policy caused.

The newly minted U.N. high commissioner for human rights during her remarks kicking off the Human Rights Council's session in Geneva also said the "attacks and persecution appear to be continuing” against Rohingya Muslims in Myanmar, according to the AP.

She called on the U.N. to collect information about human rights abuses in Myanmar to use in national and international courts in the future.

The military in Myanmar has been accused of perpetuating a genocide against Rohingya Muslims.

Bachelete also said she believes the European Union should create a search and rescue operation for migrants in the Mediterranean Sea.
