TV tonight: Alex Crawford looks back at the Yazidi genocide of 2014

Ten Years of Darkness: Isis and the Yazidis

8pm, Sky Documentaries
“Al-Hawl [refugee camp] is probably one of the scariest places in the world right now,” says Sky News special correspondent Alex Crawford. “It is packed full of Isis sympathisers or people who are connected to Isis.” She is in Iraq reporting on the humanitarian crisis that still reverberates today after the systematic slaughter of the Yazidi people in Sinjar in 2014 and the mass abductions of women and children. Bringing the Yazidi community’s fight for justice, she speaks with Kovan, who was abducted when she was 14. Hollie Richardson

More rummages through cluttered abodes for hidden treasures that could be worth epic amounts of money.

Black Snow

9pm, BBC Two
The latest episode of the superior Australian crime drama does a fine job of advancing the plot without revealing the identity of the killer. Flashbacks to the final hours of murder victim Zoe (Jana McKinnon) are a compendium of intrigue. But at the crucial moment, the personal demons of Cormack (Travis Fimmel) rear up. Jack Seale

Hacks

9pm, Sky Max
This sublime odd-couple comedy has reached new heights of gratuitous spite (but always with a weird undercurrent of love) in this fourth series as Ava and Deborah become more antagonistic and more co-dependent. Crunch time is approaching for Deborah’s show, but can she and Ava keep their game faces on for long enough to make it work? Phil Harrison

Austin

9.30pm, BBC One
Austin has always wanted to meet “Doctor Who’s best companion” Billie Piper, so naturally he drags dad Julian on the Billie Piper Magical Mystery Tour in a taxi. And in a meta move, Piper gamely turns up playing herself. She’s not the only guest star: look out for Jim Howick. HR

Film choice

Bittersweet … Virginie Efira as Rachel and Callie Ferreira-Goncalves as Leila in Other People’s Children.

Other People’s Children (Rebecca Zlotowski, 2022), 1.25am, Film4
The always top-drawer Virginie Efira gives a performance of aching vulnerability in Rebecca Zlotowski’s drama. She stars as Rachel, a single teacher for whom time is running out to have a child. Then she falls for divorcee Ali (Roschdy Zem), who has a four-year-old daughter Leila (Callie Ferreira-Goncalves). An affectionate relationship develops with the girl but Rachel is painfully aware that she will always be “an extra”. The tantalising taste of parental love when the biological mother is still around gives this wonderful film a bittersweet pull. Simon Wardell
