BEIJING (AP) — An overseas Uighur rights organization has protested the Chinese government’s use of drones in a security crackdown in the ethnic group’s home region of Xinjiang, saying it would intensify tensions that have left dozens of people dead this year.

The Washington D.C.-based Uyghur American Association demanded in a statement Monday that Beijing fully disclose its deployment of drones in an area where Chinese media say a July 28 terror attack left 96 people dead, including 59 attackers who were shot by police.
