Nobel Peace Prize laureate to speak at conference in Prague

The fresh Nobel Peace Prize laureate, the Kenyan environmentalist Wangari Maathai, is expected to visit the Czech Republic in November. Ms Maathai is supposed to take part in an international conference on greenhouse gases in Prague. The organisers had invited Ms Maathai as a regular delegate but now after she has been awarded the Nobel Prize, she'll be asked to deliver a special speech on the eve of the conference.
