Doctors Without Borders, also known by its French name Médecins Sans Frontières (MSF), announced that it will be leaving Kunduz following an attack in the hospital on Saturday.

The attack on the city of Kunduz, Afghanistan, on Saturday left 22 people dead, 12 of which were staff members from MSF. The airstrike also destroyed the intensive care unit of the health facility.

Following the attacks on Saturday, MSF issued a statement that a “war crime has been committed.” The NATO maintains a significant military role in Afghanistan but the U.S. conducts airstrikes in the country.

Both U.S. President Barack Obama and Afghanistan’s President Ashraf Ghani vowed to investigate and look into the issue. Full accounting of the circumstances is expected, but before then, Obama said that he will refrain from making judgements. The U.S. earlier stated that it may have “inadvertently struck the hospital” during the operations last Saturday but was quick to add that they will continue to work with the Afghanistan government and its overseas partners to promote security in the country.

The organisation is demanding an independent investigation as it may not be satisfied with the inquiry conducted by both governments, according to MSF general director Christopher Stokes.

The organisation said that the main hospital was “repeatedly and precisely hit during each aerial raid, while the rest of the compound was left mostly untouched.” Calls to the U.S. military and NATO made by the organisation to call off the strikes failed.

Closing the hospital will leave both the residents of Kunduz and its neighbouring districts with scarce medical care. According to the MSF, the attacked hospital is the only free trauma care medical facility in northern Afghanistan.

The humanitarian crisis in Kunduz is growing increasingly dreadful, with shops destroyed because of ongoing fighting. Roads are also impassable because of mines planted by the insurgents. The government has since launched a counter-offensive and has regained control of the city last Monday.

The Afghan government has been struggling to combat the Taliban since the U.S. and NATO assumed support and training role by the end of 2014, which officially marked the end of their combat mission in the country.
