The French rail network has been disrupted by a series of acts of sabotage, affecting hundreds of thousands of passengers - just hours before the Olympic opening ceremony gets under way in Paris. Also on the programme, a humanitarian crisis is unfolding in Ethiopia's troubled Tigray region; and, a crisis for Japanese deer as tourists behave inappropriately.
