In China, the city of Hefei has deployed a legion of robots to staff its local metro stations. Those robots help passengers find directions and assist the human workers with maintenance. Hosts Marco Werman and Carolyn Beeler have more details on what could be a glimpse at the future of rail travel in China.

Last month, five European governments shared the results of an investigation into the death of Russian opposition activist Alexei Navalny in a Siberian prison. They said Russia’s government was responsible. That's not surprising. But the means used to kill him were something new: a substance derived from South American frogs. From London, reporters Ilya Kolmanovsky and Ilya Marritz report it’s a gruesome new entry in the long history of Russian chemical killings. 

The assassination of Iran’s Supreme Leader Ali Khamenei was a jolt for Iran. But its political system is built to sustain abrupt change. History shows the regime has been able to quickly find new leaders and avert crises. From Doha, Ali Hashem, a war correspondent affiliated with the University of London, tells The World’s Carolyn Beeler that US President Donald Trump’s call for Iranians to “seize this moment” and topple the regime may be wishful thinking.  

The World's Hosts Marco Werman and Carolyn Beeler catch us up on a few stories you may have missed.

The impact of the bombing of Iran is rippling outward, drawing in multiple Middle Eastern governments through direct attacks, defensive operations and diplomatic fallout. Shockwaves are reverberating into Saudi Arabia, the United Arab Emirates, Qatar, Kuwait, Bahrain, Jordan and Lebanon. The World’s Host Carolyn Beeler speaks with Giorgio Cafiero, the head of Gulf State Analytics, a Washington DC-based geopolitical risk consultancy, about the spreading instability.

While Iran has not officially closed the Strait of Hormuz, Iran’s Revolutionary Guard Corps this weekend reportedly told ships they were not allowed through the vital sea lane, sources told Reuters. The strait is vital for the oil trade and prices have already jumped as the conflict widens. Some countries are more reliant on Gulf oil than others — that includes China, which has about half of its oil imports passing through the strait. To help understand the implications, The World's Host Marco Werman spoke to Ahmed Aboudouh, an associate fellow at Chatham House in London.

Tens of thousands of travelers — and pieces of cargo — are stranded around the globe today. That’s because several countries in the Middle East closed their airspace after the US and Israel launched strikes on Iran over the weekend. It was followed by retaliatory airstrikes by Tehran on Israel and several Gulf Arab countries with US bases, causing the widespread cancellations and delays at some of the world’s busiest airports. As The World’s Transportation Correspondent Jeremy Siegel reports, the conflict has sparked one of the most significant disruptions to air travel in recent history.

The southern Spanish region of Andalusia is embroiled in a struggle which is pitting the countryside’s traditional olive farmers against mega solar park projects. Souwie Buis has been following the developments for our partners at the Deutsche Welle, DW, program, "Inside Europe."

Three “medical totems” have just been installed at a public health clinic in Jordão, Acre, a remote area in the Amazon where the doctor-patient ratio is the lowest in Brazil. The machines are the first in a total of seven that will be placed in the area to measure vital signs and host virtual appointments. The totems, which also translate to the local Indigenous language, were developed by a doctor at the tech company Foxconn in Jundiai, almost 2,000 miles away, and funded by government subsidies. Gisele Regatão reports.

As the US and Israel continue their attacks on Iran, the capital Tehran has turned into a war zone. Residents say they are fearful for their lives. The World’s Shirin Jaafari has been in touch with some of them and brings us the latest on the ground.
