Bombs struck one of the largest hospitals in east Aleppo, Syria, today for at least the third time in as many days. The hospital is now completely destroyed, according to the Syrian American Medical Society (SAMS), which supports the facility. Only five hospitals remain operational in the besieged part of Aleppo.

The hospital, known as M10, operates underground and is the largest trauma and ICU center in eastern Aleppo. It was hit by a bunker-buster bomb that can destroy underground structures and hurt people sheltering in basements, said SAMS.
