After three years of drought thousands of colourful tents made with sticks and branches wrapped in plastic sheets and bits of cloth have sprung up among Mogadishu’s destroyed buildings. Over the summer and early autumn tens of thousands of starving Somalis entered the city. Now the refugees fill the shells of long-defunct ministries, gather in the shade of the roofless cathedral and stand under the parliament building like worshippers seeking a miracle. They appear in the streets in tattered clothing, holding bundles on their oversized heads, carrying yellow jerrycans and babies on their backs.

In the cramped living room of a run-down flat near the Aleppo frontline, two Syrian rebels sat opposite each other. The one on the left was stout, broad-shouldered, with a neat beard that looked as though it had been outlined in sharp pencil around his throat and cheeks. His shirt and trousers were immaculately pressed and he wore brand-new military webbing – the expensive Turkish kind, not the Syrian knock-off. The rebel sitting opposite him was younger, gaunt and tired-looking. His hands were filthy and his trousers caked in mud and diesel.

When at the end of May protesters in Istanbul began their occupation of Gezi Park, to stop its planned transformation into a mall, they also built barricades on the streets surrounding it. Some of the barricades were ad hoc structures: plant pots, rubbish bins, paving slabs and an occasional street sign, assembled hastily at night and lost to the police in the morning. Others were more permanent: urban fortifications made from burned-out vehicles, metal sheeting propped up against rubble from construction sites, reinforced by iron rods.

Early last year, the Houthis, followers of a revivalist anti-Western cleric, moved out of their northern highlands and marched south towards Sanaa, promising to end corruption, to fight al-Qaida, challenge US hegemony – al-Qaida and the Americans were allies in the subjugation of Muslims, they said – and raise Yemenis out of poverty and powerlessness into a shining and more dignified future. In 2011 President Saleh had been toppled to be replaced by his deputy, the aloof Abd Rabbuh Mansur Hadi, who had allowed the Yemeni branch of the Muslim Brotherhood to control many offices of state.

A Kurdish friend of mine in Sulaymaniyah in northern Iraq recently posted an image of a hand-drawn diagram on his Facebook page. With little arrows and stick figures and pictures of a train and boat or two, the diagram shows how to get from Turkey to the German border in twenty easy steps. After you’ve made the thousand-mile trip to western Turkey, the journey proper begins with a taxi to Izmir on the coast. An arrow points to the next stage: a boat across the Aegean to ‘a Greek island’, costing between €950 and €1200. Another boat takes you to Athens.
