Several United Nations staffers were killed in an attack in northern Afghanistan on Friday, authorities said.
The attack happened at the operations center of the U.N. Assistance Mission in Afghanistan in Mazar-e Sharif, said Dan McNorton, a U.N. spokesman. It followed a demonstration, he said.
"The situation is still confusing and we are currently working to ascertain all the facts and take care of all our staff," he said.
A regional police spokesman said eight U.N. staffers were killed.
The United Nations' special representative to Afghanistan, Staffan de Mistura, was on his way to Mazar-e Sharif to assess the situation, McNorton said.
