Return to the village on Ukraine's frontline

Nearly a year since the Minsk agreement was signed to try to bring peace between the Ukrainian government and Russian-backed rebels, ceasefire monitors in the east of the country say that they have seen an increase in the level of violence in some areas over the past week.

BBC special correspondent Fergal Keane has been reporting on the conflict since it began, and has returned to the embattled area around Donetsk airport and the frontline village of Peski - abandoned by all but a handful of its residents.
