Syria War : More than 280,000 people are estimated to have been killed

A twin bomb blast has killed at least 50 people and wounded many more in the northeastern Syrian city of Qamishli, near the Turkish border. More than 280,000 people are estimated to have been killed throughout the five years of bloodshed, according to the Observatory. Efforts to negotiate a lasting ceasefire have collapsed time and again. More than 4.8 million Syrians have become refugees displaced from their homeland, while more than 6.5 million people are internally displaced within the country's borders.
