Bombs struck a major hospital in Aleppo, Syria, Monday for the third time in less than a week, according to ABC News.
The hospital, known as M10, is the largest trauma and ICU center in eastern Aleppo.
Although the hospital operated underground, it was hit by bunker-buster bombs that are capable of destroying underground structures, according to the Syrian American Medical Society (SAMS).
SAMS said the bomb killed three maintenance workers and injured a nurse and ambulance driver.
The same hospital was also attacked Saturday and last Wednesday, according to ABC News.
Saturday morning the hospital was hit by seven airstrikes, which killed two patients and injured 13 more. SAMS noted that the hospital was intentionally targeted.
The hospital was forced to shut down after each attack due to extensive damage.
SAMS said Monday's attack happened while the hospital was closed, but the staff was inside working to repair the facility.
"The systematic and ongoing targeting of M10 has led to a tremendous loss for the people of Aleppo. M10 was not destroyed by bombs. It was destroyed because of the silence and inaction of the international community that knows what's happening in Aleppo," Dr. Ousama Abo El Ezz, SAMS's Aleppo Field Coordinator said in a statement.
An official with the United Nations health agency said there are now fewer than 30 doctors working in the city.
"The health system is on the verge of total collapse with patients being turned away and no medicines available to treat even the most common ailments," Stephen O'Brien, the United Nations Under-Secretary-General for Humanitarian Affairs, said in a release.
According to ABC News, up to 270,000 people are living under siege in east Aleppo and blockades have led to a shortage in medical supplies, equipment and fuel for the remaining facilities.
