During the first three months of 2019, international and pro-government forces were responsible for the deaths of 305 civilians, most from air strikes or from search operations on the groundAfghan civilians are for the first time being killed in greater numbers by US and pro-government forces than by the Taliban and other insurgent groups, a UN report released Wednesday revealed.The bloody milestone comes as the US steps up its air campaign in Afghanistan while pushing for a peace deal with the Taliban, who now control or influence more parts of the country than at any time since they were ousted in 2001. During the first three months of 2019, international and pro-government forces were responsible for the deaths of 305 civilians, whereas insurgent groups killed 227 people, the United Nations Assistance Mission in Afghanistan (UNAMA) said in a quarterly report.The majority of the deaths resulted from US air strikes or from search operations on the ground, primarily conducted by US-backed Afghan forces, some of which UNAMA said “appear to act with impunity”. In 2017, the US military started quickening its operational tempo after President Donald Trump loosened restrictions “UNAMA urges both the Afghan national security forces and international military forces to conduct investigations into allegations of civilian casualties, to publish the results of their findings, and to provide compensation to victims as appropriate,” the report states.Resolute Support, the NATO mission in Afghanistan, did not immediately respond to a request for comment. UNAMA started compiling civilian casualty data in 2009 amid deteriorating security conditions in Afghanistan.It is the first tally since records began that shows pro-government forces have killed more civilians than insurgents have. – ‘Shocking number’ –In 2017, the US military started quickening its operational tempo after President Donald Trump loosened restrictions and made it easier for American forces to bomb Taliban positions. While other nations may contribute logistical or technical support, it is US aircraft that conduct most strikes. Afghanistan’s fledgeling air force is also flying more sorties.The US has stepped up its air campaign in Afghanistan while pushing for a peace deal with the TalibanThe US has sent huge B-52 bombers on runs over the country and benefited from an increase in aerial hardware as operations against the Islamic State group in Iraq and Syria tapered off.UNAMA’s report did, however, also find that civilian casualties dropped 23 percent compared with the first three months of 2018.In all, UNAMA documented 1,773 casualties in the last quarter: 581 deaths and 1,192 injured — the lowest first-quarter toll since 2013.The drop was driven by a decrease in the use of suicide bomb attacks, but UNAMA did not know if this trend came as a result of a harsh winter or if the Taliban were trying to kill fewer civilians during peace talks.In contrast, the first three months of 2018 saw a spike in horrific attacks that skewed numbers higher for that part of the year compared to 2019. For instance, more than 100 people were killed in Kabul in January 2018 when an explosives-packed ambulance blew up.UNAMA chief Tadamichi Yamamoto, who also serves as the UN secretary general’s special representative for Afghanistan, said a “shocking number” of civilians are still being killed or maimed.“All parties must do more to safeguard civilians,” Yamamoto said in a statement.“Anti-government elements need to stop deliberately targeting civilians and using IEDs (handmade bombs), which cause indiscriminate harm; pro-government forces are called upon to take immediate measures to mitigate the rising death toll and suffering caused by air strikes and search operations,” he added.Last year was the deadliest yet for Afghan civilians, with 3,804 killed, according to UNAMA.
