Kabul and rest of the nation have witnessed several terrorist attacks in recent times.

More than 10,000 civilians have lost their lives or suffered injuries during 2017, according to the latest report by the United Nations Assistance Mission in Afghanistan (UNAMA) documenting the impact of the armed conflict on civilians in Afghanistan.

“The human cost of this ugly war in Afghanistan – loss of life, destruction and immense suffering – is far too high” said the Secretary-General’s Special Representative for Afghanistan, Tadamichi Yamamoto, during the launch of the latest annual report in Kabul.

The report detailed that in 2017, UNAMA and the Office of the UN High Commissioner for Human Rights (OHCHR) documented 10,453 civilian casualties – 3,438 killed and 7,015 injured.

The findings show that the majority of civilian casualties resulted from suicide attacks, improvised explosive device, ground engagements, targeted killings, explosive remnants of war and air strikes.
