The US journalist has made several social media pleas for the abductors of her mother Nancy to share where she is.

US television presenter Savannah Guthrie has made another emotional plea to her mother Nancy's abductors in a video she posted on social media, asking them to share her mother's location. "I'm asking you, begging you, to do the right thing now," she said. "Help us find her - tell us where to look for her." Investigators believe that Nancy Guthrie, who was last seen on 31 January, was taken against her will from her home near Tucson, Arizona, but they have not shared a possible motive or arrested a suspect. A ransom note that was sent in the days after the 84-year-old was abducted claimed she had died, according to investigators. It was one of two ransom notes believed to be credible that were addressed to Nancy Guthrie's family and sent to news media shortly after her January kidnapping. The first demanded millions in Bitcoin for her release; the second stated that she had died, according to US media, which cited unnamed sources. In her latest video posted on Monday, Savannah Guthrie addressed the possible kidnappers. "Our family is in agony. We are in a nightmare that will not end. Nothing about our situation has changed. We have done our part, and we will never stop looking for her. We will always ache for her and feel that hole in our hearts." She added: "Help us bring this situation to an end. For all of us, no matter where we've been and what we've done, I believe there is always a way home. Please make the right choice."
