"As of 1 October 2017, more than 809,000 Rohingyas are estimated to be sheltering in Bangladesh, having fled violence and persecution in Myanmar. Violence which began on 25 August has triggered a massive and swift refugee influx across the border - an estimated 509,000 people have arrived in the space of a month. These refugees have joined some 300,000 people who were already in Bangladesh following earlier waves of displacement. The Rohingya population in Cox?s Bazar is highly vulnerable, many having experienced severe trauma, and are now living in extremely difficult conditions. The existing refugees, along with the unprecedented volume of new arrivals, have put immense strain on infrastructure, services and the host population, overwhelming existing response capacity. Most who have arrived came with very few possessions. They are now reliant on humanitarian assistance for food, and other life-saving needs. Population movements remain highly fluid, with people settling into pre-existing makeshift or spontaneous sites before infrastructure and services have been established. Many sites are now alarmingly overcrowded, exacerbating risks to people?s security, safety and wellbeing. In these highly congested conditions there is an increasingly high risk of an outbreak of disease. Many of the new arrivals are visibly traumatized and disoriented, suffering from the consequences of extreme violence, from the loss of or separation from family members, and from the ordeal of displacement. Rape, human trafficking, and survival sex have been reported among the existing perils for women and girls during flight. Children?s well-being and mental and physical development is affected by the incidents that led to their flight and there are growing numbers of separated and unaccompanied children being reported. Most newly arrived children have not been able to access education since they arrived. Protection interventions and up-scaled outreach and referrals are needed to ensure that protection responses and services reach those most in need. The Government of Bangladesh has triggered a wide response across Ministries, agencies, and the Military, and on 14 September allocated 2,000 acres of land for the establishment of a new camp. Local communities have been at the frontline of the response, providing food and basic items for new arrivals. National and international humanitarian agencies have rapidly responded in support of Government efforts. However, the scale of needs dramatically exceeds our current capacity to deliver. A rapid scale-up and comprehensive humanitarian response by all partners is critical at this stage. The Rohingya Refugee Crisis Response Plan is focused on life-saving and protection assistance for the most vulnerable people. The Plan targets 1.2 million people, including all Rohingya refugees, and 300,000 Bangladeshi host communities over the next six months. The plan prioritizes the provision of life-saving assistance, improving the conditions and management of settlement areas, as well as promoting protection, dignity and respect for the Rohingya refugees. The plan also factors in a contingency for new arrivals that are anticipated in the coming months, as the influx continues day to day. Given the scale and the possibility of a rapid deterioration of conditions, which could turn the crisis into a catastrophe, partners remain committed to the principle that our plans must be grounded in capacity. We urge more experienced partners with relevant expertise to join the response, so that we are better able to cover urgent needs and save lives..."
