(UN News) – A brutal terrorist attack which killed at least 50 civilians in Afghanistan over the weekend is an “atrocity” and may amount to a war crime, the top United Nations envoy to the country declared today as he condemned the indiscriminate suicide bombing in “the strongest terms.” On 23 November, a suicide attacker detonated an improvised explosive device in a sports field in the Yahyakhail district of Afghanistan’s southeastern province of Paktika. At least 50 civilians who were attending a volleyball match were immediately killed while another 60 were injured. According to reports, many children were among the dead and injured.
