For civilians, the last four years of the war have been the deadliest, with more than 3,400 civilians killed each year from 2014-2017, according to data from the and the .

"We are concerned that we will see greater harm this year unless necessary steps are taken by all parties to prevent civilian casualties," Tadamichi Yamamoto, the UN Secretary-General's special representative for Afghanistan.

Administration officials acknowledge that they expected the Taliban to respond to the increase in military pressure with more violence.

The increase in violence has been devastating for the Afghan people. According to the UN Assistance Mission in Afghanistan, which tracks , more than 3,400 Afghan civilians have died and more than 6,800 Afghan civilians have been injured in each of the past four years of the war.

Afghan officials that about 10,000 Afghan security forces died last year, a significant increase from previous years. Fearing that the publication of the numbers could undermine morale and hinder ongoing recruitment efforts in Afghanistan, the US military has begun the records.
