Shelling by Syrian rebels on government-controlled areas has become a daily occurrence, causing more injuries than before.

This is footage of rebels launching rockets toward a government-controlled area. Though limited in power, the self-made rocket can threaten the existence of an entire building.

Back in May when we first visited Aleppo this year, people being attacked by shelling told us of their desperation and anxiety over the future.

"At about 11 a.m. on April 28th, a rocket hit this area when I came home. Many neighbors were killed and injured. We really don't know what to do. Now I have no home, no place to live. Where should I go? Where should I spend the night? I really don't know," said Abdul Kader, local resident.

3 months later, and the situation is worse. Recent confrontations have made the number of injuries rise even higher.

To learn more, we went to the only 2 public hospitals that still accept patients. And here is the disturbing scene we found in the emergency room.

It's hard to imagine what happened to these innocent people.

All family members of the patients refused our requests for an interview. After seeing all these horrifying scenes, it is understandable that their sorrow is beyond words and to talk about the past can only hurt their wounded hearts again.

The doctors told us these two public hospitals receive 90% of those injured. Even those who first went to a private one end up being transferred to these hospitals. There has been a big wave of patients since August.

"We have had more than 1,000 different injuries this month. And 30 of them are in critical condition. In 40 cases, the patients are permanently or temporarily handicapped," said Dr. Zaher Hajio, Central Hospital of Aleppo University.

Doctors from both hospitals tell us they can see from patients' injuries that the rebels began using deadlier weapons this month.

"We have witnessed lately a big development in the kinds of weapons that the armed groups are using. We know this by examining the injured bodies. The wounds are more serious because the weapons are now more lethal," Dr. Zaher Hajio said.

"Most of the patients we have received lately are more serious cases, and it looks like highly explosive weapons are being used more by the armed groups," said Dr. Muhammad Bateekh, Alrazi Hospital.

Though the supply road for the government-controlled area is unstable, the doctors tell us the hospitals have enough medicine and tools for now. But due to the daily shelling, the blood bank is always short on supply.

So far, there's no end in sight for the crisis. And the people of Aleppo still have to spend their days and nights with the sounds of bombing.
