Beirut blast: Rescuers search for survivors

We dedicate the programme to the explosion in the port area of the capital Beirut in Lebanon. Rescuers are still searching for survivors; at least 100 people died in the blast and thousands were injured.

We explain what is known so far about the cause of the explosion and reach out to people in the city who have been affected. One of them is Pascal, whose wife was injured in the explosion and had to have five surgical procedures on her face after glass flew into it. He describes the situation in the hospital last night as chaotic with "blood everywhere and people screaming and crying".

We also bring together a group of people living in and around Beirut to hear how the past 24 hours have been for them. And we get BBC experts to help answer questions by our listeners around the world about the explosion, and about Lebanon, the country that continues to grapple with economic and political crisis.
