South Korea mourns after Halloween crush

Distraught relatives in the South Korean capital Seoul have been visiting hospitals and a missing persons centre in search of people who may have been injured or killed in a crush on Saturday. At least 153 people died in the disaster in an alleyway in the Itaewon district. We speak to someone who was there. Also in the programme: we hear from one of the first medics on the scene of Saturday's car bomb attacks in the Somali capital, Mogadishu, which killed more than 100 people; and why British cathedrals are being bathed in sound and light.
