On 30 December 2007, Israeli Prime Minister Ehud Olmert issued an order requiring approval by both the Israeli Prime Minister and Israeli Defense Minister of all settlement activities (including planning) in the West Bank. The change had little effect with settlements continuing to expand, and new ones being established. On 31 August 2014, Israel announced it was appropriating 400 hectares of land in the West Bank to eventually house 1,000 Israel families. The appropriation was described as the largest in more than 30 years. According to reports on Israel Radio, the development is a response to the 2014 kidnapping and murder of Israeli teenagers.
