Kate Adie presents stories from Moldova, Russia, the US, Cuba and Indonesia.

In Moldova, a knife-edge victory for the Yes vote in the country's referendum on EU membership came as a shock to many. Chisinau and the EU have accused Russia and its proxies of ‘unprecedented’ interference. Alongside the referendum, the country’s pro-Europe president was also running for re-election. Sarah Rainsford was on the border with Transnistria.

Moscow’s push into the Donbas in eastern Ukraine is intensifying, as Russian troops seek to gain control of the whole region. Earlier this year, Ukraine made its own incursion into the Russian border regions. Nick Sturdee has followed the story of some Russian-speaking Ukrainian fighters who are now in Kursk.

Mike Wendling paid a visit to the swing state of Wisconsin as Halloween preparations were underway and found people are not just spooked by scary masks and ghoulish stories – there’s a deeper, palpable anxiety among voters in Wisconsin about dirty campaign tactics, and even the fate of US democracy itself.

In Cuba, the electricity supply often fails when the fuel runs short. They have regular, planned black-outs, but last weekend, the whole of Cuba suffered a complete blackout, as it dealt with the aftermath of Hurricane Oscar. Will Grant has been to one village, where living without electricity has become the norm.

Mini the Macaque was taken from the forest in Indonesia, when she was just days old, and sold on to criminals in a global animal torture ring. Mini - and the monkey who was held captive with her - were eventually rescued after a BBC Eye investigation. Rebecca Henschke went along to see them being freed.
