The article is talking about an explosion that happened at the Al-Alhi Baptist Hospital. There is a video that shows the moment the explosion happened, and it was so big that it lit up the sky. The explosion happened on the hospital grounds and caused a cloud of fire and smoke to rise up into the air.
In this passage, it is described that there was a state of panic in a building, which happened to be a hospital. Dr. Fadel Na’eem, who is in charge of the orthopedic department, explains that he was in the middle of performing a surgery when a very loud blast occurred within the hospital. As a result, chaos broke out as hospital staff rushed into the operating room, shouting for assistance and informing others about the numerous injured individuals.
Dr. Na’eem further explained in a recorded video for CNN that he had just finished one surgery when suddenly a massive explosion took place. Initially, they believed the explosion happened outside the hospital because they never expected the hospital itself to be targeted and bombed.
