Migrant Girl Dies After Crossing Mexico-US Border

US media reports that a seven-year-old girl, who had crossed illegally the Mexico-US border, has died of dehydration and shock. The Guatemalan girl was part of the group of migrants who say they are fleeing persecution, poverty and violence in their home countries of Guatemala, Honduras and El Salvador. We are connecting with one of the reporters travelling with migrants.

Also today, the closing session of the climate conference in Poland is taking place, and we have gathered audience questions to put to one of the BBC environment correspondents there.

And, we hear from people with neurofibromatosis, a genetic disorder that causes tumours to grow along their nerves.
