In the final two months of 2016, as the four-year siege of the rebel-held city of Aleppo ended in brutal fashion, the four more-shared stories were all shared more than 300,000 times. The best performing story (about how people could help civilians trapped in Aleppo) was shared more than half a million times, almost entirely on Facebook.However, in January and February this year, as the Syrian regime and Russian forces bombarded the enclave of Eastern Ghouta, the most viral piece across all publishers (a BBC News article about children struggling to survive) was shared just 42,000 times.
