GEORGE OURFALIAN/AFP/Getty Images(ALEPPO, Syria) — Syrian government troops moved deeper into east Aleppo Monday and airstrikes continued to pound the area as medics attempted to treat some of the wounded in makeshift clinics.

Plans are underway meanwhile for U.S. Secretary of State John Kerry to meet this week in Geneva with Russian Foreign Minister Sergei Lavrov to discuss a proposed withdrawal of all rebels against the Syrian government from east Aleppo. Lavrov told a news conference Monday that rebels who stay in that area will be treated as terrorists once a deal is reached.

“We will treat them as such, as terrorists, as extremists, and will support a Syrian army operation against those criminal squads,” the Russian official said.

A nurse in east Aleppo told ABC News Monday that “yesterday, we escaped death.” The nurse, Baraa, who didn’t give her last name, said that on Sunday, she was stitching a child’s leg wound when the clinic was hit by an airstrike.

“The bombardment started above us like rain,” she said, adding that she ran away from the strikes with some of her friends at the clinic. The child she was treating had been wounded from another airstrike and brought to the clinic for treatment.

“While I was stitching him a brutal airstrike happened. The electricity shut down,” Baraa said. The child is wounded, but not in danger, she said.

On Monday, airstrikes continued to pound east Aleppo. Heavy clashes took place in the al-Shaar neighborhood, where Syrian government troops advanced, according to the Syrian Observatory for Human Rights.

Anas Moughrabieh, a doctor in Michigan with the Syrian American Medical Society, said nurses inside Aleppo have been calling him to say goodbye. A few days ago, he said some nurses tried to reopen east Aleppo’s M2 hospital, which had been out of service. They consulted with him about two patients over the phone.

“One made it to life and the other one was moderately sick,” he said over a messaging app. “I asked them to prematurely give up on the sicker one and I felt bad to tell them it is a luxury now to care for patients with this level of illness with this limited resources. They didn’t give up on him until their location was discovered and attacked with barrel and cluster bombs.”

Hamza Khatib, a doctor in east Aleppo who uses a pseudonym, said the hospital where he works has been receiving more than 300 injured people every day.

“The situation is madness,” Khatib told ABC News. “We have lost a lot of lives, most of them are civilians. Now, the regime has managed to take a part of the already besieged city, and a lot of people are crowded in a smaller area. That means that each rocket, each missile will produce a bigger amount of injuries and death.”

He said he had been in east Aleppo since 2012 and the current offensive on the besieged city is the worst he has ever seen.

“We are under attack,” the doctor said. “We have the feeling that the whole world has abandoned us, left us here in Aleppo to be killed brutally with no help at all. We can’t defend ourselves. We can’t do anything. We can’t protect our hospitals. We can’t protect our lives. We can’t protect our patients’ lives. We can’t protect our families’ lives. It’s desperate here.”

Syrian government forces and rebels also clashed in brutal fights in east Aleppo’s al-Zebdieh neighborhood Monday as the government and its allied forces attempted to advance, according to the Syrian Observatory for Human Rights. Abdulkafi Alhamdo, a media activist in al-Zebdieh, said his neighborhood was probably shelled 100 times in half an hour.

“A massacre maybe just 50 meters away from my house, people on the ground,” he said, adding that some people who came to the area to help were injured when more bombs hit. “No cars dare to come to help them. It’s horrific,” he said.

East Aleppo hasn’t received United Nations aid since July. Residents live with little access to water, food, health care or fuel for heating. Some of the people who left east Aleppo neighborhoods that have been seized by the government have moved into Alhamdo’s building, he said. On Monday, one of them, a child, knocked on his door.

“He was holding a jug, asking me for clean water, even a cup for his little sister and asked me for a bottle of water just to clean the cups,” said Alhamdo. “He said, ‘Uncle, I know we are disturbing you with our requests but what should we do?'”

Alhamdo said the boy was about to cry. He said the boy thanked them before leaving with two bottles filled with water.
