The Queiq (Modern Standard Arabic: قويق, Quwayq, [quˈwajq]; North Syrian Arabic: ʾWēʾ, [ʔwɛːʔ]), with many variant spellings, anciently known as the Belus (Greek: Βήλος, Bēlos) and Chalos, and also known in English as the Aleppo River, is a river and valley of the Aleppo Governorate, Syria and Turkey. It is a 129 kilometres (80 mi)-long river that flows through the northern Syrian city of Aleppo. It arises from the southern Aintab plateau in southeastern Turkey. The Akpınar River in the Kilis plain is one of the headwaters of the Queiq. The former town of Qinnasrin lay on its banks. It partly flows along the western rim of the Matah Depression. The valley has been occupied for thousands of years and in ancient times the Queiq valley was noted for its flint industries and pottery.
The river dried up completely in the late 1960s, due to irrigation projects on the Turkish side of the border. Recently, water from the Euphrates has been diverted to revive the dead river, and thus revive agriculture in the plains south of Aleppo, but many Syrians remain bitter towards the Turks over their handling of the river.
In late January 2013, during the Syrian Civil War, the bodies of approximately 110 men and boys, most with hands bound behind the back, mouths sealed with tape, and gunshot wounds to the head, were found on the edges of the river in a part of Aleppo controlled by opposition forces. Very few of the victims were over 30. Many victims showed signs of torture.Human Rights Watch reported that family members of many of the victims testified that they were last seen in a government-controlled area or after they set out to cross into the area through two checkpoints, one manned by opposition forces and the other by government forces. Most of the families interviewed by Human Rights Watch insisted that the victims had not been involved with the armed opposition or actively participated in demonstrations. They said, in many cases, that the victims were merchants. Some had shops in the government-controlled area but lived in the opposition-controlled area, and others regularly crossed into the government-controlled area to buy supplies that they sold in markets in the opposition-controlled area. The victims are believed to have been detained, tortured, executed, and dumped by government forces(according to opposition) into the river over a period of several weeks. The bodies floated downstream from a government held portion of the river into a rebel held portion in the Bustan al-Qasr district. The bodies only became apparent when the winter high waters receded in late January. In February, a grate was lowered from a bridge into the river in opposition held territory to help catch other bodies floating down.
