A handout satellite image released on February 7, 2017 by Amnesty International shows the military-run Saydnaya prison, one of Syria's largest detention centres located 30 kilometres (18 miles) north of Damascus. As many as 13,000 people were hanged in five years at the notorious Syrian government prison near Damascus, Amnesty International said on February 7, 2017, accusing the regime of a "policy of extermination." / AFP PHOTO / Amnesty International / Handout
