For weeks, President Donald Trump has been threatening to attack Iran and he’s sent what he called an ‘armada’ of combat ships and fighter jets to the region. He’s mentioned two main reasons for the military build-up there: Iran’s nuclear programme and the killing of protesters in the country.

International news organisations are often refused visas to report from inside Iran, so it’s difficult to know exactly how many protesters were killed, but some human rights groups say it could be more than 6,000 people.

In this episode we answer some of your most commonly-searched questions; why is the US threatening to attack Iran, why doesn't President Trump want Iran to have nuclear weapons and what could happen if conflict broke out?

Bhajan clubbing is India’s latest cultural trend. People across the country are swarming to bhajan concerts. Instead of club music and vodka shots, they’re enjoying devotional music, chanting and chai. But it’s still high energy with lots of production, like lasers. Many have praised the events for offering a wholesome alternative to traditional clubbing and a nice way to connect with like-minded people. Lots use the opportunity to get dressed-up in their best traditional glitz too.

And even Prime Minister Narendra Modi has phrased the movement saying: ‘Our Gen-Z is taking to bhajan Clubbing... it is spirituality and modernity merging beautifully, particularly keeping in mind the sanctity of the bhajans’.

So what’s it like at a bhajan club? We’re joined by two friends Pari and Muskan who have attended an event in Delhi. They share why they loved it so much.

For some of us, measles might sound like a childhood disease from the past that our grandparents worried about. But it can have a severe effect on your health if you catch it as an adult and in some regions, infections are rising. Indonesia, Pakistan and South Africa have all dealt with recent outbreaks. And in the countries like US - that were previously recognised as having eliminated the disease - there’s been a rise in cases as well. So - why is the virus on the rise and what does vaccine hesitancy have to do with it?

BBC Health reporter Nick Triggle explains what the virus is, where it’s most prevalent and why we’re seeing a downturn in vaccination rates in some regions. Canada lost its measles elimination status late last year - Nadine Yousif, a BBC reporter in Toronto, explains how anti-vax content on social media may have contributed to this.
