Note:
I swapped the original article at the request of a mod to from a source deemed more reliable, but to avoid confusion when reading the comment section prior to this edit, here is the link to the original article. I chose the Relief Web source listed by some who commented. Cheers!
The correct way to to cite it would be: ‘OHCHR has confirmed the killings at Al Awdabuilding […].’
Its simply wrong to not do it. Especially cutting of the sentence at a ‘,’.
And the last time a crime against humanity was still under investigation – where it was obvious that a rocket hit a hospital, but the exact circumstances where still unclear – it was later confirmed that Hamas hit the hospital.
