Ukraine: Rustem Umerov set to be new defence minister

Ukraine is to get a new defence minister - but why now in the middle of the counteroffensive against Russia? And what difference will it make? Also in the programme: the first ever Africa Climate Conference opens in Nairobi, with a focus on finance; we hear from the new head of the UN's Green Climate Fund, set up to help developing countries. And school teachers in South Korea go on strike over bullying by parents.
