When it comes to conservation, adorable and majestic animals often attract the most concern for their plight. It's not so easy to get the public's attention when it comes to animals that are perceived as weird or creepy or downright unpleasant.

Globally, around 70% of vultures are now under threat of extinction and Nigeria's vultures are no exception. BBC West Africa journalist Makuochi Okafor has been investigating this story.

 In Vietnam, The Last Empress, a new film inspired by the life of the final empress of the Nguyen Dynasty, appears to be provoking a strong reaction. Nam Phuong is a well-known historical figure in Vietnam, who along with her husband, Bao Dai, she was also seen as a puppet of the French colonial regime. Since the release of the trailer for The Last Empress, this long debate in Vietnam has bubbled back to life. Duc Ha from the BBC's Bangkok bureau has been exploring the human story behind all the politics and controversy.

In a private party in a Russian town, Katya was about to blow out the candles on her 30th birthday cake when masked men burst into the nightclub that she had hired and began physically and verbally attacking her friends. The swoop was instigated by a vigilante group who want to accelerate President Vladimir Putin's promotion of what he sees as traditional Russian family values. As is sometimes the case in these raids, members of the town's police also joined them, shutting down the party and interrogating the guests. Amalia Zatari of BBC Russian has been looking into this vigilante group.
