The Afghan government has said that Taliban fighters were inside and shooting from the hospital, CBS News correspondent Mark Phillips reports. Vickie Hawkins, Executive Director of MSF U.K., told Phillips that those comments are "outrageous."
"They are to an extent justifying the destruction of a fully functioning hospital," Hawkins said.
The Afghan and U.S. governments have pledged a full investigation, which could take some days. President Barack 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.
In the center of Kunduz, shops opened and people were seen walking the streets Monday, said Sarwar Hussaini, spokesman for the provincial police chief. Government troops have largely cleared the militants from the city after launching a counter-offensive last Thursday, he added.
Kunduz is an important city on the Tajikistan border, a hub for smuggling routes for drugs and guns to and from Central Asian countries, and alcohol into Afghanistan, officials have said.
The multi-pronged Taliban assault on Kunduz last Monday took the Afghan authorities by surprised and hugely embarrassed President Ashraf Ghani's administration. The Taliban held the city in their grip for three days before largely melting away as the counter-offensive reclaimed Kunduz.
But they left destruction in their wake. Qayum Khan, a resident reached by telephone, described corpses on the streets but could not tell if they were civilians or insurgents. Grocer Sardar Wali said he felt it was "normal ... so I have opened my shop."
Elsewhere, a Taliban attack on the far western city of Maymana, capital of Faryab province bordering Turkmenistan, was repelled by Afghan forces on Monday. The province's deputy governor, Abdul Satar Barez, said the city came under the attack from four directions on Sunday night.
"It was a similar attack to that in Kunduz and the aim of the enemy was to overrun the city," he said.
