Number of Syrian refugees
Since the Syria conflict erupted in March 2011, more than four million people have fled the country and the United Nations reports almost 6.6 million people are displaced in Syria. More than half are children.
Syrians are fleeing a protracted conflict that has rendered 13.5 million people inside Syria in need of humanitarian assistance, according to the United Nations. Of those, more than 5.6 million are children.
Humanitarian assistance is needed by about 4.6 million people who are in places that are besieged or hard-to-reach areas.
The number of Syrian refugees in Lebanon has risen to about 1.2 million, making up almost 20 per cent of the population.
More than 600,000 Syrian refugees are in Jordan. Unsurprisingly, this is putting immense strain on the host communities.
There are approximately 4.6 million Syrian refugees in Jordan, Lebanon, Turkey, Iraq, North Africa and Europe.
Number of people killed and injured in Syria
Over five years of fighting in Syria has killed more than 470,000 people, according to the United Nations. 76,000 of these casualties happened last year alone.
About 1.5 million people have been wounded or permanently disabled, according to the Syrian Observatory for Human Rights.
According to the World Health Organisation there are continuing attacks on Syrian health facilities, ambulances and health workers. As at September 2015, 58 per cent of Syria's public hospitals had been destroyed or were only partly functional.
