The World

Today on The World we get the latest round in the FBI versus Apple. Also, our partners at Frontline managed to get cameras into the hands of some prominent Saudi activists. The results give an amazing, at times horrific, picture of what daily life is like in the Saudi Kingdom. Plus, we hear music from Guatemalan rapper Rebeca Lane and Indian sitar player Anoushka Shankar.

Lahore and Brussels: Two cities a world apart are now feeling the pain of terrorist attacks. First, we hear from Lahore, the Pakistani city where a suicide bomb attack killed dozens of people at a park where Christian families were celebrating Easter. A Taliban splinter group has claimed responsibility. Then we head to Brussels, where one father struggles to make sense of the attacks last week and explain them to his young sons...

Belgian authorities launched more anti-terror operations in Brussels today following the attacks there earlier this week. We also hear about the centennial of an Irish rebellion against British rule known as the Easter Rising. Plus, we stick a song in your head that will probably be with you all weekend. Hint: It's a tune with roots in Cuba, but is popular all over the globe.

Brussels seen from the inside and out: We'll have the latest on the mood in the city two days after deadly terror attacks there. Then we'll turn to Istanbul to get Turkish reaction to the attacks. Plus, we get a look at the faults in Belgian security that allowed the suspects to slip through the intelligence cracks...

Belgium begins three days of national mourning for the victims of Tuesday's terror attacks in Brussels. Marco speaks with a Belgian playwright who has written extensively about Islamic radicalization in Belgium. We'll get his reaction to the attacks in Brussels, and ask him what Belgium needs to do now to stop further violence. Away from Belgium, we look at President Obama's post-Cuba stop in Argentina — and controversy there about the timing of his visit.

We're devoting the show to two major stories today. First, we're following the aftermath of what authorities in Belgium say were twin terrorist attacks in Brussels. We'll also get the latest from the Belgian capital, look at the wider European response, and speak with a security expert who recently returned from Brussels. Plus, President Barack Obama's ongoing visit to Cuba, which wraps up today...

President Obama is in Havana for day two of his historic three-day visit to Cuba. We'll head to Havana to hear how the city is welcoming the president and hear from a Cuban dissident who isn't pleased with Obama's decision to try to reset relations with the Castro regime. Plus, we take a trip to Little Havana in Miami to gauge reaction to the trip among Cuban-Americans...

We're taking The World on the road today with a special show out of station KPBS in San Diego. Marco Werman and Global Nation editor Monica Campbell are co-hosting a special show that will bring you stories of life along the US-Mexico border. We'll go with a couple of Border Patrol old-timers as they reflect on the relative quiet of the California-Mexico border today versus the early 1990s. We'll also meet veterans of the US military who ended up being deported to Mexico...

Surfing the tides in Brazil, Facebook and nudity, and a look back at the secret story of the last presidential visit to Cuba.

Donald Trump and Hillary Clinton solidified their leads in Tuesday's primaries. We want to know what Russians make of the frontrunners.
