At least 1,129 people have been killed and 3,442 wounded in the Ukraine conflict since mid-April, UN monitors in the country said in their fourth monthly report on Monday.

UN High Commissioner for Human Rights Navi Pillay said in a statement that increasingly intense fighting in the Donetsk and Luhansk regions was extremely alarming and the shooting down of a Malaysian airliner on July 17 may amount to a war crime.
