Libya floods: death toll continues to rise

The United Nations says the number of people known to have been killed in last week's floods in north-eastern Libya has reached about 11,300. It says another 10,100 people are still missing in the city of Derna alone.

Also in the programme: the Italian city of Venice introduces a daily tax for tourists to try to ease crowding on the busiest days of the year; and Europe is currently facing a potentially deadly invasion of red fire ants.

Joining host Audrey Brown to discuss this and more are Taran Khan, an Indian journalist and writer, and Marcus Chown, British science journalist and writer.
