The US and Iran have agreed to a conditional two-week ceasefire, hours after President Trump threatened that "a whole civilisation” would die if the Strait of Hormuz did not reopen.

Iran has agreed to open the key shipping route while the US stops its strikes— but it’s also put forward a 10-point plan with several other demands, including compensation for the damage caused by the war.

Pakistan has been acting as a mediator between the two countries and it will host talks between the US and Iran this Friday - so what can we expect from the negotiations?

In this episode we look at the terms of this ceasefire, what it means for the countries involved in the conflict and what could happen next.

Israel has intensified its attacks on Lebanon this week. It’s as the US-Israel war with Iran also continues. A new front in the war opened in Lebanon on 2nd March when the Iran-backed group Hezbollah fired rockets at Israel. This was in retaliation to the death of Iran’s supreme leader and ceasefire violations.

More than a million people in Lebanon - roughly one in every six - have been displaced from their homes. And more than 1,400 people have been killed.

We chat to the BBC's Middle East correspondent Hugo Bachega, who’s based in Beirut. He walks us through what’s happening in Lebanon, the background to Hezbollah, and when the war might come to an end.

Lebanon, Kenya and Jamaica are among the handful of countries that have gotten rid of the ‘period tax’ - the additional charge the government adds to the retail price of sanitary products like pads or tampons. Now, a new campaign has started to scrap the tax in Pakistan. According to UNICEF, the tax can add up to 40% to the retail price of sanitary pads in the country, making them out of reach for many women and girls, especially in impoverished communities.

Mahnoor Omer, the 25-year-old lawyer from Pakistan who has started a legal case to cut the tax, talks us through attitudes to periods in her home country and explains why this campaign is so important to her. And we hear from young women in Pakistan who tell us what they think of the tax.

For the first time in more than 50 years, NASA is taking humanity back to the moon with its Artemis II mission. The crew is made up of four astronauts, including the first woman astronaut and the first black astronaut to travel to the moon. They will blast off from the Kennedy Space Center in Florida, in a spacecraft never used by humans before, and begin their journey to orbit around the moon.

The launch is expected to happen on 1 April - but NASA are keeping their options open, and have named six other potential dates. So - when will the launch take place? And once it does, how long will it take the mission to reach the Moon?

The BBC’s science correspondent Georgina Rannard unpacks it all for us — and tells us everything we need to know about this historic mission. And we hear from two members of the Cosmic Girls Foundation - Vanessa from Finland and Ximena from Venezuela - who share their reaction to the mission and their hopes for how it could push the boundaries of science.

The United Nations has voted to recognise the transatlantic slave trade as the “gravest crime against humanity”, after a proposal from Ghana. It comes after years of campaigning from African and Caribbean nations, calling for reparations for the largest long-distance forced movement of people in recorded history.

But not all governments supported the vote. The US, Israel and Argentina voted against it and 52 countries - mostly members of the EU - decided not to take part. The wording of the resolution has received criticism, with some arguing it implies that some crimes against humanity are worse than others.

So what does this vote mean - and how could it change the way we look at this chapter of history in the future?

BBC Africa reporter Daniel Dadzie joins us for this episode to explain it all - along with two students based in Accra, Malisecullen and Abena. We also hear from Meghan in the US, who shares her thoughts on her country rejecting the vote.

A 20 year old woman in the US has successfully sued Meta and YouTube over her childhood addiction to social media, winning $6million in damages.

Jurors found that Meta, which owns Instagram, Facebook and WhatsApp, and Google, owner of YouTube, intentionally built addictive social media platforms that harmed her mental health.

This result is likely to have implications for hundreds of similar cases now winding their way through US courts. Meta and Google said they disagreed with the verdict and intended to appeal.

In this episode BBC tech correspondent Joe Tidy explains the arguments made in the trial and whether this decision could lead to any changes in the way they work. And we hear your views on whether you think these apps are addictive and what you make of the ruling.
