There are celebrations in Bangladesh following Prime Minister Sheikh Hasina’s resignation after weeks of violent unrest. Many have described the past month as one of the worst periods of violence seen in Bangladesh since the country formed five decades ago. Student protests against quotas in government jobs escalated into an anti-government movement after a violent crackdown by security forces and pro-government student groups have seen around 400 people killed. The country remains in a state of chaos after the Prime Minister hastily fled the country before protestors stormed her official residence. Until recently, 30% of civil service roles in Bangladesh were reserved for the children and grandchildren of people who fought for the country’s independence back in 1971, a system protestors said benefitted those close to the ruling party. Protestors share their experiences and our BBC reporter in Dhaka, Akbar Hossain, explains how the student protests changed course and dramatically ended the 76 year-old leader’s 15 year reign. We also hear from Rani Singh, who previously interviewed Sheikh Hasina at her palace.Instagram: @bbcwhatintheworld Email: whatintheworld@bbc.co.uk WhatsApp: +44 0330 12 33 22 6 Presenter: Hannah Gelbart Producers: Kevyah Cardoso and William Lee Adams Editor: Emily Horler and Rosanna La-Falce

Animals are essential in maintaining ecosystem balance, but in some cases they can have the opposite effect. In the coastal city of Mombasa, Kenya, authorities are looking to cull 1 million Indian house crows. Conservationists say they are becoming a nuisance and have significantly reduced the number of small indigenous birds in the region. So how will they be dealt with? The BBC’s Dorcas Wangira, an Africa health correspondent, explains. Pest are an issue in New York too. There’s estimated to be 3 million rats scurrying around the Big Apple and the city’s mayor has made it his mission to deal with the rocketing number of rodents by hiring a ‘rat tsar’. Sam Cabral, a BBC reporter in New York, tells us more. Finally, we hear from Predator Free Wellington, an organisation in New Zealand, which is hoping to completely remove predators (like rats and possums) by 2050.
