The deadliest wildfires to hit the US in over a century have turned vast swathes of the island of Maui to ash and taken the lives of at least 99 people. The governor of Hawaii, Josh Green, has warned that the number killed will rise as only 25% of the affected area has been searched so far. On the Sky News Daily, Niall Paterson hears from our US correspondent Martha Kelner, who is in Maui, about the devastation she's seen there and the questions being asked by locals about a sophisticated warning system that failed to alert them to the imminent danger.
