At least 80 people were killed and another 231 wounded Saturday after an explosion tore through a protest in Kabul by minority Shiite Hazaras, Reuters reported. “Opportunist terrorists” took advantage of the protest to kill and wound “a number of our countrymen, including security and defense personnel,” President Ashraf Ghani said in a statement released after the incident. The Islamic State claimed responsibility for the attack, according to the group’s media branch, Amaq. The protest was organized by ethnic Hazaras, a minority Shiite group in the predominantly Sunni country. They were demanding that authorities run a power line through their poverty stricken home province of Bamyan, in keeping with the original plan for the power line. The plan was changed in 2013 in what many Hazaras say is proof that the government discriminates against them.
