Seeing first hand a testament of what one city has endured. This is where the conflict has been at its fiercest. Before the war 50,000 people lived here. In the last 18 months Saada has become a key battleground – the heart of the Houthi rebellion and the target of more airstrikes than any other Yemeni city.

Paul has lived rough here on the Isle of Wight (UK) for months, but he's now one of 14 homeless people with a permanent berth on-board. Top deck the seats are out and the beds are in.

With worldwide concern growing about the decline of bees, there's been a renewed interest in creating sanctuaries for these key pollinators to thrive. One of them is in the heart of the British capital.

These rooftop hives in the heart of the city provide more than 10 kilos of honey a year - plus by-products - like beeswax.
