On 14 May 2011, during the Syrian revolution, the Syrian military began an operation in the Syrian town of Talkalakh. The government said that it was targeting terrorist groups, while the Syrian opposition described it as a crackdown against pro-democracy protesters.
It occurred a day after a mass demonstration against the rule of Syrian president Bashar al-Assad. Many residents fled to Lebanon, and this incident is considered one of the first events that triggered the migration of refugees from Syria.
On 15 May, the Syrian military entered the town of Talkalakh, on the border with Lebanon. Reports subsequently emerged that the military was massacring members of the Syrian opposition. The reports were mostly from civilians fleeing over the Kabir river into Lebanon to escape the violence.
By 19 May, the military concluded its operation and began withdrawing from Talkalakh.
