US defense officials say that around a dozen US troops were “disciplined” over last year’s US attack on a Doctors Without Borders (MSF) hospital in Kunduz, Afghanistan, an attack which killed 42 civilians.

Officials declined to identify any of the troops, except to say it included both officers and enlisted personnel, and no generals. No criminal charges were filed against anyone over the killings, condemned as a war crime. Most were simply “administrative” rebukes, though a handful faced letters of reprimand, which are likely to harm the soldier’s chance of promotion.

The Pentagon has offered several excuses for the attack, which all boil down to the incident being an accident and no one really being at fault, but the US has also loudly opposed the idea of an international investigation, as demanded by MSF officials.

MSF declined comment on the reports that no criminal charges will be filed, saying they are holding off judgement until the Pentagon communicates with them or makes a public statement, as opposed to anonymous officials just leaking the news.
