This is the Global News Podcast from the BBC World Service.

I'm Nick Miles and at 30 Nours GMT on Tuesday, the 6th of June, these are our main stories.

There is severe flooding in parts of southern Ukraine after the destruction of a major dam.

Prince Harry is in court alleging journalists illegally gathered information about him.

And the Brazilian singer Astorud Gilberto, who brought bossa nova to the world with her version of the girl from Epanima, has died at the age of 83.

Also in this podcast, the end of an era in Singapore.
