The 39-year-old was all smiles as she entered the United Nations headquarters in New York City, where she celebrated the announced investigation into the crimes against humanity committed by ISIS in Iraq.
Clooney has been at the forefront of pursuing the case on behalf of UN Goodwill Ambassador Nadia Murad and other Yazidi victims.
“This resolution is a victory for victims of ISIS who have fought for so long for justice,” Clooney said in a statement released by her Doughty Street law firm in London.
“Through its unanimous vote today the UN has sent a strong message that ISIS can no longer commit genocide, crimes against humanity and war crimes with impunity. And that victims may finally have their day in court.”
Speaking to the BBC, Clooney added, “For the first time the UN is saying to ISIS terrorists that if they commit genocide, crimes against humanity and war crimes they will be held to account in a court of law and it’s saying to the victims that their voices will be heard.”
Earlier this month, the British lawyer released a statement addressing threats of forcible detention made against another high-profile client, former Maldives President Mohamed Nasheed.
“Any attempt by a Maldivian diplomat to detain President Nasheed in Sri Lanka would constitute a violation of international law as well as Sri Lankan criminal law,” Clooney said in a statement.

“President Nasheed should not be returned to the Maldives to serve a sentence that resulted from a sham trial, and it is incumbent on the Sri Lankan authorities to ensure that his rights are respected while he is in their country.”
Nasheed was charged with terrorism in 2005 and sentenced to 13 years in prison after a controversial trial. Clooney and her legal team have argued that Nasheed had been wrongfully imprisoned and that his detention was in violation of international law.
Nasheed was granted asylum in the U.K. in May 2016.
Clooney made her first public appearance since welcoming twins Ella and Alexander at the Venice Film Festival with husband George last week. The radiant couple stepped out for the premiere of George’s latest film Suburbicon and stunned on the red carpet.
George opened up about the dangerous nature of Amal’s work in an interview with French outlet Paris Match before the twins’ birth and said that they have decided to be cut back their travel to risky areas of the world.
“We decided to be much more responsible, to avoid the danger,” the actor tells the magazine. “I won’t go to South Sudan any more or the Congo, Amal will no longer go to Iraq and she’ll avoid places where she knows she isn’t welcome.”
