The United Nations says Islamic State (IS) militants have executed dozens of people this week in the northern Iraqi city of Mosul, which government forces are battling to retake from the extremists.
The office of the UN High Commissioner for Human Rights said IS militants executed 40 civilians on November 8 after accusing them of collaborating with Iraqi government forces.
Their bodies were then hung from electricity poles in several districts, the office of the UN office said, citing sources.
The November 11 statement said IS militants appear "to be continuing to carry out killings based on decisions of its self-appointed "courts.'"
Also executed was a man who had violated an IS ban on using mobile phones, the statement said.
The UN said another 20 civilians were shot dead on November 9 at the Ghabat military base in northern Mosul.
The executions came as Iraqi forces, backed by U.S. air strikes and Kurdish Peshmerga fighters, advanced deeper into Mosul.
