The large blast that targeted Syrian evacuation convoys on Saturday and killed at least dozens of residents who were evacuated from the rebel-besieged towns of Foua and Kefraya in Idlib province under a deal reached between the Syrian government and rebels, has brought the focus back to the evacuation deals signed between the Syrian regime and opposition armed groups.

Since 2014, the Syrian government and the armed opposition groups have reached a series of reconciliation agreements in a number of besieged areas, mainly aiming at allowing armed opposition fighters to leave government-besieged cities and town to opposition-held areas in northern Syria , near the borders with Turkey.

These deals also offer civilians the opportunity to flee conflict zones and allow entry of humanitarian aid into war-afflicted areas. International actors involved in the Syrian conflict such as Russia , Iran and Turkey have been acting as mediators.

While the Syrian government positively regards such reconciliation agreements, armed opposition groups and activists, however, view them as "compulsory displacement" aiming at reshaping the demographic population structure of the country.

"The compulsory deportation agreement in Al Waer neighbourhood in Homs came to announce the forceful entrance of the Russians in line with the [regime's] demographic change plans targeting all those who are regarded by the Syrian regime as part of a 'useful Syria', under the patronage of Russia," wrote Syrian activist and writer Omar Kokash in reference to the recent swap deal carried out on April 8 in Al Waer neighbourhood, the last opposition-held district in Homs, with some 2,500 people expected to leave.

Here is a timeline of the main "people evacuation" agreements that have been implemented since 2014 until the present day.
