I am one of the very last doctors serving the remaining 300,000 citizens of eastern Aleppo.

Atrocities are being committed every day. The Syrian regime and Russian aircraft are systematically targeting civilians and hospitals across the city.

We have seen no real effort from President Trump, Chancellor Merkel or Prime Minister May to prevent the criminal attacks against civilians and our hospitals.

That is why I've started this petition. World leaders are not listening to my voice alone. Will you join me and make a call so loud they can’t ignore us?

For five years, we have borne witness as countless patients, friends and colleagues suffered violent, tormented deaths. For five years, the world has stood by and remarked how ‘complicated’ Syria is, while doing little to protect us.

Last month there were 42 attacks on medical facilities in Syria, 15 of which were hospitals in which my colleagues and I work. At this rate, our medical services in Aleppo could be completely destroyed in a month, leaving 300,000 people to die.

What pains me and my fellow doctors the most is choosing who will live and who will die. Young children are sometimes brought into our emergency rooms so badly injured that we have to prioritise those with better chances, or simply don’t have the equipment to help them. A few weeks ago, four newborn babies gasping for air suffocated to death after a blast cut the oxygen supply to their incubators. Their lives ended before they had really begun.

Despite the horror, we choose to be here. We took a pledge to help those in need. We have a duty to remain and help. All we ask now is for Trump, Merkel, May and other world leaders to do their duty, too.

We do not need their tears or sympathy or even prayers, we need them to act. We need them to prove that they are the friends of Syrians.

Please join us in our call. Ask world leaders to save the people of Aleppo.
