Andrew Harding reports on Rwanda's presidential election, due on Monday. There's no real doubt who'll win. In the last election, President Paul Kagame took more than ninety percent of the vote. And he's faced no major challenge this time round. Rwanda lives in the shadow of the 1994 genocide that swept away eight-hundred-thousand lives. The Russian republic of Chechnya is now supposed to be at peace. And the war-torn capital, Grozny, is being impressively rebuilt. But killings and disappearances are still common. Over the years, large numbers of Chechens have left their troubled homeland. Many of these exiles chose to leave, but as Lucy Ash has been hearing..others were given no option. This time two years ago tensions in the Caucasus exploded. Moscow sided with the tiny territory of South Ossetia in a war with Georgian forces. And within days the Russians had won a crushing victory. But the Georgians have forgotten nothing. They see themselves as victims of vast injustice. And as Tom Esslemont explains, they're passing that message on to the next generation.... The Cuban revolution was played out very much in front of the cameras. Photographers made the revolutionary leaders famous around the world. But in Havana, Christine Finn came across a less well-known cache of images. And they shed light on a friendship between Fidel Castro and a remarkable Cuban explorer and adventurer. On hot summer days the parks and gardens in Europe's cities seem more valuable than ever. The islands of greenery are a refuge in the heat of the concrete sea. And the heart of the German capital, Berlin is blessed with many allotment and garden areas. But now, as Joanna Robertson has been finding out, some of these open spaces are in danger of being lost.
