Israel-Hamas war: Mounting international alarm over possible ground offensive into Rafah

There are mounting concerns over Israel's planned offensive into Gaza's southern city of Rafah.

The World Health Organization is also making clear that its contingency plans in the event of an invasion would serve as no more than a "band-aid" for casualties. Sarah Coates reports.
