The largest city in north Darfur, Sudan is surrounded by paramilitary forces. Food and water is scarce. Locals fear the city is about to fall imminently. We hear from a leading United Nations diplomat who has a simple but dire warning.

We go to Israel for reaction to the pro-Palestinian demonstrations at American universities.

And we go to Brazil where deadly heavy storms and flooding have caused a hydroelectric dam to collapse.
