Iran: the funeral of Ayatollah Ali Khamenei

James Coomarasamy introduces stories from Iran, Russia, Ukraine and Algeria.

The extended mass public mourning for Iran's former Supreme Leader Ayatollah Ali Khamenei went on for days - and millions of Iranians attended the official processions to mark his passing. Lyse Doucet describes what she saw amid the crowds in Tehran.

Ukrainian drones have repeatedly hit fuel installations in Russia - leading to shortages at many petrol stations and long queues for motorists. James Landale spoke to a number of drivers in Moscow about their trouble getting on the road, and who they hold responsible.

Despite signs of new military assertiveness from Ukraine, the country is still suffering severe human losses from the war. Lucy Ash visits a pioneering psychological retreat for battle-weary troops, and hears what they struggle with even after returning from the front lines.

In the Algerian capital, the storied Casbah neighbourhood is full of reminders of the country's independence struggle. After decades of neglect and decay, its maze of alleways and historic buildings are now undergoing a slow process of restoration. Philip Sweeney recently revisited Algiers to see how the district is remaking itself.
