Life in Lebanon is a daily battle to beat the power cuts caused by the country's chronic electricity shortage. If you live in a block of flats, you have to time when you go in and out to avoid getting trapped in the lift. Food goes bad because fridges don't work, families must often choose between air-conditioning and watching TV, and those on life-support machines live in constant fear of a switch-off. But if it's hell for citizens, it's heaven for operators of illegal private generators who profit by filling the gap left by the failures of the national grid. Some are former warlords who led militias in Lebanon's civil war. They're given an unofficial licence to operate, often in return for favours to the authorities in Lebanon's chaotic and often corrupt sectarian system. Now a huge protest movement is demanding change in Lebanon - and a constant power supply is one of the demonstrators' main demands. They want to break the power of the "fuel mafia" that imports diesel for the generators and has close links to the country's leading politicians. For them, the fight for light is a fight against corruption. But can Lebanon's feeble state ever manage to turn all the lights on?

There’s a new climate of fear in Sri Lanka. This time it’s the Muslim community who are fearful of the future. The Easter bomb attacks in Sri Lanka - targeting churches and international hotels - horrified the island. It’s suffered civil war but never known jihadi violence. But the attacks also intensified a creeping campaign by the Sinhala Buddhist majority against the Muslim community - with Muslims murdered, their businesses burned or boycotted. Jill McGivering investigates the growing climate of fear now driving many Muslims to emigrate and casting a shadow over those left behind.
