The Israeli army says it has killed dozens of what it calls "terror operatives" in the north in Gaza City. Meanwhile, officials from Gaza's Hamas-run health ministry are reporting more than 100 people killed in the past 24 hours. More civilians are relying on the UN's aid agency for Palestinians, UNRWA, for food and shelter - as disease spreads in overcrowded conditions.

Also in the programme: we hear from one family in Odesa living through Russia's wave of drone and missile attacks on Ukraine; and the story of a mother who took on one of Mexico's most violent cartels and the case against culling Switzerland's wolves.
