US "speeding up evacuations" from Kabul

The US says it's speeding up its evacuation efforts at Kabul airport; we hear how large crowds of Afghans desperate to escape the Taliban, are still trying to push their way in. Also in the programme: details emerge of a deadly attack on civilians and soldiers in the Sahel region of West Africa; and as the UN and Fridays for Future say a billion children are severely threatened by climate change, we hear from a young activist in the Philippines.
