The Russian Defence Ministry announced on Friday that a ceasefire would take effect in the rebel-held region of Idlib in northwestern Syria.
Activists in Idlib province have been calling for Syrians to protest against the regime’s bloody assault, which began in late April and has killed 1,248 people according to Syrian first responders. At least 450,000 people have been displaced with refugee camps being unable to take them in.
The Syrian conflict began in 2011, following the brutal suppression of protests by the Assad regime.
