MAKLI (AFP) - On a hillside in flood-ravaged southern area, a famous Sufi burial site is crowded with families - their pilgrimage less about religious devotion than the simple matter of survival. With night about to fall, tensions rise at the makeshift camp, where hunger and anger are feeding a growing sense of anarchy as the flood victims look down from the black hills on their water-logged villages. Hussain Mala, 25, from Sajawal, a city of 120,000 people about 50 kilometres away which has been lost for now to the floods, sits with a dozen other young men watching the traffic for signs of aid trucks bringing food. For the month of Ramazan, the Iftar time is the most tense, as hunger pangs grow after a long day under a blazing sun. Tens of thousands of peasants displaced by the floods have fled to the rocky hillsides, some camped in shade amid mausoleums of chiselled stone, others grazing their flocks between the graves of thousands of Sufi saints. They wait for 7:00 pm to come when they can join their families for Iftar, but only a few fleeing the floods in haste were able to come with food supplies and aid handouts are scarce. We save the food and money we have for our children so they can survive, said Ghulam Qadir, in his 50s, sweat pooling around the band of his purple turban. The bazaars in the nearby city of Thatta are empty, since the authorities ordered the evacuation of its 300,000 inhabitants at the weekend, exacerbating the food crisis. An aid agency van stops in front of a small group of women and children begging for supplies - a hand throws out a box filled with supplies and the vehicle sets off again immediately, escaping the dozens of people already starting to run down the hills in its direction. Sometimes to prevent a fight erupting, charities en route to an official relief camp will hand over bags of flour, pulses, rice or sugar, though it is not enough for the starving young men who often try to cling to the trucks. Theyre treating us like animals. They just throw food boxes, without taking care of who gets it - so people fight between each other - or they dont give anything, said Hussain. Two or three of our people have broken legs or arms from falling from the trucks, he said. Despite the escalating tension, police said the situation was under control besides some minor incidents. But authorities say they are worried, and try to direct the displaced families to camps away from the floods that have wreaked most devastation in Sindh where Makli lies. Weve set up a relief camp for 40,000 people in Karachi, but no one turned up there yet, said Zulfiqar Mirza from the Sindh interior ministry. We guarantee that they will get all the assistance they need there. That wont convince Babur Salangi, 31, also from Sajawal, who like many others thinks that there is no support in the camps. I am grateful to the government because they saved our lives by sending trucks to take us, he said. But how can I celebrate Iftar? Everything I have left is this, he said, pointing at the tatty green shirt covering his back.
