Hello! published the first official photos of baby Shiloh Jolie-Pitt

Jolie taped the message for the United Nations Refugee Agency (UNHCR) in April, before the birth of her daughter with Brad Pitt, Shiloh.

One Spanish TV station has been running the clip twice an hour, according to a United Nations spokeswoman.

The actress has been a goodwill ambassador for the UNHCR since 2001.

In the 30-second message she says: "For the millions of displaced persons around the world, please help keep their hope alive and remember World Refugee Day."

The UNHCR says there are now 8.4m refugees around the world.

Official pictures

Earlier this week, Hello! magazine threatened to take legal action to stop websites publishing a leaked picture of Jolie and Pitt with their newborn daughter, Shiloh.

The couple sold the rights to the first official photos of the baby through picture agency Getty, with all proceeds going to charity.

US magazine People is believed to have paid $4m (£2.2m) for the North American rights.

Hello! has not disclosed how much it paid for the pictures.

The celebrity couple say they have no plans to get married

The leaked photo first surfaced on US gossip blogs Oh No They Didn't and Defamer on Wednesday.

Interview

In their first television interview since the birth of their daughter, Jolie and Pitt thanked the people of Namibia, where the couple are currently based.

"They've been so gracious and made our stay here very special," Pitt told the Namibian Broadcasting Corporation.

"We've had an incredible time with our family exploring the country, and a truly peaceful birth of our daughter."

Baby Shiloh Nouvel Jolie-Pitt was born on 27 May under a veil of secrecy.

In their TV interview, the new parents thanked Namibians for the privacy they have enjoyed during their stay.

Bodyguards and undercover Namibian police officers have shielded the couple from journalists, erecting green cloth screens around the beach resort where they are staying.
