Amnesty: At least 13,000 hanged at Syrian 'slaughterhouse' since 2011

Syrian authorities have killed at least 13,000 people since the start of the 2011 uprising, in mass hangings at a prison north of Damascus known to detainees as "the slaughterhouse", Amnesty International has said.

In a new report covering the period from 2011 to 2015, Amnesty said 20-50 people were hanged each week at Saydnaya Prison in killings authorised by senior Syrian officials, including deputies of President Bashar Assad, and carried out by military police.
