the Israel Central Bureau of Statistics. "The Israeli CBS also collects statistics on the rest of the West Bank and the Gaza District. It has produced various basic statistical series on the territories, dealing with population, employment, wages, external trade, national accounts, and various other topics." The Palestinian Authority however use Nablus, Jenin, Tulkarm, Qalqilya, Salfit, Ramallah and Tubas governorates as administrative centers for the same region. The Shomron Regional Council is the local municipal government that administers the smaller Israeli towns (settlements) throughout the area. The council is a member of the network of regional municipalities spread throughout Israel. Elections for the head of the council are held every five years by Israel's ministry of interior, all residents over age 17 are eligible to vote. In special elections held in August 2015 Yossi Dagan was elected as head of the Shomron Regional Council. Israeli settlements in the West Bank are considered by some in the international community to be illegal under international law, but others including the United States and Israeli governments dispute this. In September 2016, the Town Board of the American Town of Hempstead in the State of New York, led by Councilman Bruce Blakeman entered into a partnership agreement with the Shomron Regional Council, led by Yossi Dagan, as part of an anti-Boycott, Divestment and Sanctions campaign. Archaeological sites Ancient city of Samaria/Sebaste The ancient site of Samaria-Sebaste covers the hillside overlooking the West Bank village of Sebastia on the eastern slope of the hill. Remains have been found from the Canaanite, Israelite, Hellenistic, Roman (including Herodian) and Byzantine periods. Archaeological finds from Roman-era Sebaste, a site that was rebuilt and renamed by Herod the Great in 30 BC, include a colonnaded street, a temple-lined acropolis, and a lower city, where John the Baptist is believed to have been buried. The Harvard excavation of Samaria, which began in 1908, was headed by Egyptologist George Andrew Reisner. The findings included Hebrew, Aramaic, cuneiform and Greek inscriptions, as well as pottery remains, coins, sculpture, figurines, scarabs and seals, faience, amulets, beads and glass. The joint British-American-Hebrew University excavation continued under John Winter Crowfoot in 1931–35, during which time some of the chronology issues were resolved. The round towers lining the acropolis were found to be Hellenistic, the street of columns was dated to the 3–4th century, and 70 inscribed potsherds were dated to the early 8th century. In
