On February 2, 1982, Syrian forces began to crush resistance in the city of Hama, where a Muslim Brotherhood-led revolt had occurred. Much of the city was devastated; depending on whose numbers are used, between 10,000 and 40,000 may have died. In those pre-YouTube, pre-Twitter days, it took some time for the outside world to understand the scale of the massacre.
Today, for the first time in 30 years, Syrian rebels are able to mark the anniversary. While the international community debates, Syria's conflict continues.
