16 years, thousands dead and no clear end in sight

America's longest war continues to trudge on and the bodies continue to pile up.

The summer of 2017 has been a bloody one in Afghanistan, with the death toll numbering in the hundreds. Suicide bombers have targeted funerals and banks. A massive blast in June killed at least 150 in the capital of Kabul. Another this month rocked a Shiite mosque. According to the United Nations, the number of civilians killed in a six-month period reached an eight year record high.
