In 2014, the fourth year of the conflict in Syria, a bleak humanitarian situation deteriorated even further. To date, there have been over 200,000 fatalities and one million casualties. Three million people have sought refuge across borders and more than seven million people have been displaced. More than half of the country's population - including five million children - require some form of humanitarian aid. Not only has violence increased, but access to aid has also been restricted. Needs are greater than ever but the aid system is not meeting them. Today, Syria remains the most serious humanitarian crisis in the world.
