Citing Russia’s Ministry of Defense, Russian media outlets report two Russian medical specialists were killed and another injured when militants shelled a mobile military hospital in Aleppo. 

One Russian medic was killed immediately at the Russian military mobile hospital set up in western Aleppo, and another died later in a hospital after succumbing to her injuries, the Russian Defense Ministry said.

The doctors are now fighting for the life of Russian pediatrician, who was also severely injured in the attack.

“Today, between 12:21 and 12:30pm [local time], a medical center of the Russian Defense Ministry’s mobile hospital in Aleppo was shelled by the militants during the reception time,” Major-General Igor Konashenkov, a spokesman for the Russian Defense Ministry, told journalists on December 5.

Some local residents attending medical appointments were reportedly also injured during the shelling that targeted one of the field hospitals set up in the government held part of the city.

“We demand that the international community, as well as the International Federation of Red Cross, Red Crescent Societies, Doctors without Borders (MSF), and other international organizations strongly condemn this deliberate killing of Russian military medics that were fulfilling their duty of care by treating Aleppo residents,” Konashenkov said, adding that the crime would be investigated, and all those responsible would be brought to justice.

Noting that, as Western colleagues claim, all al-Nusra Front terrorists were cornered in Eastern Aleppo's southern part by the Syrian Army, Konashenkov said they were unable to deliver such precise fire, according to Sputnik news agency.

The spokesman underscored that militants of the Syrian "opposition" were "undoubtedly" behind the attack.

The Russian Defense Ministry attributes the blame for the hospital shelling to “terrorists and their patrons in the US, the UK and France.”

“It is beyond doubt that the shelling was conducted by the ‘opposition’ militants. Moscow understands who gave the Syrian militants the coordinates of the Russian hospital right at the moment when it started working,” Konashenkov said.

“Full responsibility for the killing and injuring of our medics, who were treating children in Aleppo, lies not only with the actual perpetrators [of this crime], that is with the ‘opposition’ militants. The blood of our military personnel is on the hands of the people who ordered the hit … [on the hands] of the terrorists’ patrons from the US, the UK, France and other terrorist sympathizers,” Konashenkov said.

RT news agency has requested comment on the shelling of the Russian hospital from the office of the UN High Commissioner for Human Rights, as well as the Red Cross, Human Rights Watch, Human Rights First, and Amnesty International.

In response to a request from RT, Amnesty International said it is trying to check whether it is “able to comment on this.”  “But usually if we have not documented and been able to verify details for ourselves it can be tricky for us to provide a comment on specific attacks,” the emailed response reads.

“Repeated attacks on healthcare and other civilian infrastructure throughout Aleppo” indicated that “all sides to the conflict in Syria are failing in their duties to respect and protect healthcare workers, patients and hospitals, and to distinguish between them and military objectives,” the Red Cross told RT in a comment following the shelling of the hospital.

“Healthcare infrastructure, medical personnel and the sick and wounded are protected under international humanitarian law (IHL). They must not be attacked,” the Red Cross stressed, adding that “when hospitals come under fire, countless numbers of people are deprived of life-saving healthcare.”

“The hospital was far from the frontline. Now it’s totally destroyed,” Vladimir Savchenko, the head of the Russian Reconciliation Center in Syria told journalists earlier.

“The hospital was in open terrain and had clear identification markings – it was clearly seen,” Savchenko said, adding that the militants “still used this situation and carried out a massive strike against [the facility] … in defiance of the international regulations, of the humanitarian law that forbids the shelling of hospitals.”

RT’s Lizzie Phelan reports from Aleppo that the city is subject to non-stop shelling by the militants and the hospital that was targeted was overcrowded with injured civilians, including children.
