In February 2011, Physicians for Human Rights-Israel reported that some 190 Eritrean and Ethiopian refugees were being held hostage in Sinai, and that numerous refugee women reported having been raped on their trip to Israel. In 2013, the same organization estimated that about 1,000 refugees were being held in Sinai hostage camps, and that in total about 7,000 refugees had been abused in these camps, resulting in more than 4,000 deaths. In a 2013 report, This American Life reported on the experiences of journalist Meron Estefanos, who has helped publicize the kidnappings, and helped get some hostages freed. The Egypt–Israel Peace Treaty of 1979 limits the number of Egyptian forces that can be deployed in Sinai. After the Egyptian Revolution of 2011, security forces largely abandoned the peninsula, but they returned in 2014 to fight unrelated terrorist networks, and the practice of kidnapping refugees moved to Libya and elsewhere.
