There has been continuous carnage in Afghanistan. Last week, more than 200 people were killed, many at a girls school in Kabul. The violence comes as the U.S. and NATO are withdrawing troops, scheduled to be gone completely by September. Amna Nawaz speaks with Afghan President Ashraf Ghani about the situation and whether he expects the ongoing violence to get worse as U.S. troops exit the country.
