Since then most of these small camps have been closed and IDPs instead concentrated at the Menik Farm site. Menik Farm is located in the far south-west of Vavuniya District near the district’s border with Anuradhapura and Mannar districts. The site straddles the A14 Mannar-Medawachchiya road and the disused Mannar railway line. The site is very close to the Aruvi Aru and other rivers and streams. One of the Aruvi Aru’s tributaries actually cuts the site into two. With a population in excess of 200,000 Menik Farm is believed to be the largest IDP camp in the world. It has also become one of Sri Lanka’s largest settlements. The following camps/hospitals are being or have been used to house the IDPs displaced from the Vanni region since October 2008:       A number of hospitals in other districts have also been used by the IDPs. When the camps were initially established in early 2009 the Sri Lankan government stated that it expected to hold the IDPs in the camps for as long as three years. However, on 7 May 2009 the Sri Lankan government announced plans to resettle 80% of the IDPs by the end of 2009. This was reinforced on 21 May 2009 when President Rajapaksa gave assurances that most of the civilians would be resettled within 180 days. By July the resettlement target was being revised downwards. On 10 July President Rajapaksa stated that there was "target", not a promise, to resettle 50-60% of the IDPs by the end of November 2009. However, on 16 July 2009 in a letter of intent to the International Monetary Fund (IMF) the Sri Lankan government stated that it "aimed" to resettle 70-80% of the IDPs by the end of 2009. The IMF subsequently approved a US$2.6 billion loan to Sri Lanka. By the end of August 2009 less than 12,000 IDPs (5%) had been released or returned to their places of origin. The imminent monsoon raised concern amongst the aid agencies/international community. The Sri Lankan government reacted to this by returning more IDPs to their places of origin. Some of these IDPs were held in military run "closed" transit sites in their home districts, from which they can’t leave and access by aid agencies is heavily restricted. Some IDPs were allowed to return to their homes but most of these homes are located inside high security zones, such as the Jaffna islands, which are under the strict control of Sri Lankan Navy.
