American reconstruction efforts In an effort to bring economic development to the area, Zabul province's first airstrip was built just outside the city in 2006. It is a dirt runway. The first flight brought in supplies for Provincial Reconstruction Team Zabul and other organizations trying to rebuild the area. Three years later, a girls school was built to attempt to improve education in the area. An initial school supply and prayer mat donation was made, and regular book drops and school supply donations were made until the PRT left in 2013. Clean water programs around the city improved the availability of clean water sources. In 2009, efforts were completed to improve the water system at the old Qalat City Hospital to bring clean drinking water to patients there. Not all the reconstruction efforts were successful, however. In 2006, construction began on a new economic district for the city. Meant to be an area of commerce and development, ten million dollars and three years later, most of the buildings are unoccupied, unusable either due to lack of the skills to maintain the buildings or due to a lack of need for the building. Zabul province's governor refused to move into the new house, citing the lack of security. Anne Smedinghoff, a 25-year-old U.S. diplomat, was killed by a suicide car inside the city in the spring of 2013.
