(Al Jazeera) – With Syria’s civil war entering its sixth year, hundreds of civilians are being killed weekly and at least 1.9 million continue to live under siege, lacking access to life-saving humanitarian aid. Few international aid agencies have been allowed to deliver relief supplies or to work within the country; those that have, are doing so at the high risk of being targeted. Doctors Without Borders (MSF), is one of several humanitarian aid NGOs whose hospitals and medical personnel have repeatedly been attacked in Syria. The organisation operates a support programme to approximately 70 healthcare facilities run by Syrian doctors, where it provides medical supplies, salaries, advice among other services.
