Star concert honours Nobel winner
Tom Cruise and Oprah Winfrey hosted a concert in Norway to honour Nobel Peace Prize winner Wangari Maathai.
The concert in Oslo featured performances from Joss Stone, Andrea Bocelli and Patti Labelle.
Professor Maathai was accompanied to the event by Norway's Crown Prince Haakon and Princess Mette Maarit.
The 64-year-old Kenyan received the Nobel Prize for her environmental work saving trees in Africa and promoting ecological, social and economic reforms.
It is estimated her dedication has seen up to 30 million trees planted across Africa.
She was the first African women to receive the prestigious Nobel Peace Prize.
Leading a tribute to Prof Maathai, actor Cruise repeated her words: "People fight over water, food and natural resources, she said recently.
"When our resources get scarce, we go to war over them. In managing our resources, and in sustainable development, we plant the seeds of peace."
Cruise added that he was "exceptionally proud" to be hosting a tribute to the environmentalist.
Winfrey struggled to hold back tears as she was joined on stage by Prof Maathai, who wore traditional dress for the occasion.
Other performances on the night came from Cyndi Lauper and Tony Bennett, who all appeared for free at the concert which will be broadcast in more than 100 countries.
