In 2015, humanitarian organizations continued to face a range of obstacles from the Israeli authorities regarding the access of personnel, especially national employees, and the materials needed for humanitarian projects. These include physical and administrative restrictions on the access and movement of humanitarian actors; restrictions on the delivery of materials needed for humanitarian projects; and limitations on the implementation of projects that involve building, expanding or rehabilitating infrastructure in the Gaza Strip and Area C of the West Bank. Such obstacles have hampered the ability of humanitarian organizations to provide assistance and protection to Palestinians throughout the oPt. Humanitarian operations in Gaza were also impeded by restrictions imposed by, and the prohibition on contact with the Hamas authorities, in addition to the prolonged closure of the Rafah crossing with Egypt.
