Heavy fighting around Gaza’s main hospitals

We hear from doctors as heavy fighting is reported around Gaza’s main hospitals, and from an Israeli military spokesperson. Videos show a missile hitting an area where people were taking shelter in Al Shifa hospital, followed by screams. A BBC correspondent in Gaza says Israeli tanks are now just metres away from the hospital, surrounding it from four sides.

Also on the programme, we hear from the first ever summit dedicated to preserving, glaciers, ice sheets, poles and all of the other the frozen parts of planet Earth. And images of a creature known as "Attenborough's Echidna," thought to have been extinct, have been newly filmed in Indonesia. We hear from one of the expedition members.
