John Kerry announces Syria 'ceasefire' Thursday February 11,2016

U.S. Secretary of State John Kerry last night Thursday February 11,2016 said a 'pause' in hostilities between Syrian forces and Western-backed rebels would begin in a week after a crisis meeting in Munic,Germany

The working group of 17 countries met in Munich to hold crisis talks and announced a nationwide ceasefire

John Kerry announced the agreement alongside his Russian counterpart Sergei Lavrov

 The nationwide ceasefire, which is expected to begin in a week's time, will provide humanitarian relief to hundred of thousands of Syrians fleeing the fighting and who have been besieged

But, crucially, neither Bashar Al Assad's government nor opposition groups have said whether they will obey the truce. 

The deal also does not apply to Russian airstrikes which have been supporting advances by Syrian troops.

And it doesn't include either ISIS or Al Qaeda's affiliate Jabhat al-Nusra which hold swathes of the country and contribute to much of the fighting.
