Iran Press/Iran news: Iran's Foreign Minister Mohammad Javad Zarif wrote on Twitter on Sonday that the US military presence in Afghanistan is the root cause of the problems in the country.
US troops stormed into Afghanistan in November 2001 in an invasion that followed the September 11, 2001 attacks on the World Trade Center and the Pentagon.
Last month, a study by the Brown University's Watson Institute for International and Public Affairs said hundreds of thousands of people have been killed due to the so-called "war on terror" launched by the United States in the wake of the 9/11 attacks, including 38,480 civilians in Afghanistan.
An estimated 2,798 civilians have been killed and 5,252 others wounded in attacks across the country from January to September this year, according to the United Nations Assistance Mission in Afghanistan (UNAMA).
Afghanistan's President Ashraf Ghani meanwhile said in November that 28,529 Afghan security forces had been killed since the start of 2015, a figure far higher than anything previously acknowledged. That is an average of about 20 soldiers killed every day.
