The Syrian Observatory for Human Rights (SOHR) said on Monday that it continues to monitor and track the arrests and killing under torture in Syrian regime prisons and security centers. The Observatory said that 969,854 people, including 155,002 women, were arrested by regime security services since the outbreak of the Syrian Revolution in March 2011. While thousands of them were killed throughout the years, and many were released, nearly 140,000 civilians, including 29,344 women, remain detained and their fate remains unknown, it added. SOHR documented by name the death of 49,410 Syrians under torture inside the regime security camps: 48,994 young and adult men, 349 children under the age of eighteen, and 67 women. The Syrian Observatory has been informed that the number of people who died in the camps reached 105,000 people. Over 83 percent of the total death toll were killed and/or died in these camps between May 2013 and October 2015. SOHR sources have also confirmed that more than 30,000 detainees were killed in the notorious prison of Saydnaya alone, while the second-largest percentage of killings occurred in the Air Force Intelligence. The Observatory warned against the repercussions of non-complying with international accords signed by Syria, as well as the ongoing indifference by the warring powers in Syria to the issue of killing under torture. SOHR urged attaching the highest significance to this issue and making the voice of the detainees and their families heard by the world. Moreover, it warned against using laws of counterterrorism to justify arrests of politicians and human rights activists. It also called for the inspection of detention centers across Syria, especially in regime-held areas, so that the conditions of detainees are unveiled. Furthermore, the fate of the missing and detainees who have been killed must be disclosed, SOHR added.
