KABUL - A new study called Costs of War produced by Brown University's Watson Institute for International Studies has said that war in Afghanistan since 2001 US-led invasion that sparked insurgency has left almost 100,000 people dead and wounded the same number, US media reports.

War in Afghanistan since the 2001 U.S.-led invasion sparked insurgency killing 100,000 persons, and wounding as many others.

The study looks at war-related deaths, injuries and displacement in Afghanistan and Pakistan from 2001 to last year, when international combat troops left Afghanistan.

Civilian and military deaths in both countries total almost 149,000 people killed, with 162,000 seriously wounded, its author, Neta Crawford, found.

Most civilian deaths happened after 2007, with more than 17,700 civilian deaths recorded by UNAMA between 2009 and 2014. Most civilians were killed by militants, she said. (Pajhwok)
