Kate Adie presents stories from Lebanon, Sri Lanka, Ukraine, Cuba and Somalia.

Israel says it has killed the Hezbollah leader, Hassan Nasrallah, as it continued its air offensive against Lebanon. It says this week’s airstrikes are in response to rocket attacks across the northern border into Israel by Hezbollah. According to the UN, more than 90,000 Lebanese have been displaced over the past week. Hugo Bachega spoke to residents who were forced to flee their homes.

Sri Lanka has elected left-wing President Anura Kumara Dissanayake, who's seen something of a meteoric rise. His election heralds a paradigm shift in the country, which has had a history of right-wing administrations - but his rise is perhaps best understood through the prism of the country's dire economic crisis says Samira Hussain in Colombo.

Vlodymyr Zelensky travelled to the US this week as he continues to seek approval for the use of long-range Western missiles, and to set out his 'victory plan' to President Biden. Back in Ukraine, the threat of Russian forces is ever-present, as Abdujalil Abdurasulov found on a recent trip to the eastern front.

Cuba has become known among tourists for its low crime rate - though reputation has been tarnished in the eyes of many Cubans, who say they now are genuinely worried about rising crime, especially with the emergence of a cheap new drug on the island, reports Will Grant.

Somalia has been torn apart by more than 30 years of overlapping conflicts and now faces a further threat: climate change. But even as a warming world is turbo-charging Somalia’s problems, Justin Rowlatt discovered that it's also inspiring entrepreneurs to find solutions that could prove transformative.
