The U.S. and Afghan governments vowed Sunday to jointly investigate the attack on a hospital in Kunduz that killed 22 people, as street-by street battles continued between government forces and Taliban fighters.
Amid accusations that U.S. jet fighters were responsible for what Doctors Without Borders said was a "sustained bombing" of their trauma center in Kunduz, President Barack Obama and Afghanistan's President Ashraf Ghani promised investigations.
Obama said he expected a full accounting of the circumstances surrounding the bombing, and that he would wait for those results before making a judgment.
He said the U.S. would continue working with Afghanistan's government and its overseas partners to promote security in Afghanistan.
Some top U.S. officials said the circumstances surrounding the incident remain murky, but others indicated the U.S. may have been responsible.
