A delicate deal
A cease-fire negotiated by Russia, Iran, and Turkey took effect in Syria at midnight Friday, hours after the Syrian government and opposition groups signed onto the agreement on Thursday. The truce does not cover the Islamic State and the al Qaeda affiliate in Syria. The U.K.-based Syrian Observatory for Human Rights said the deal appeared to be holding in its first hours, despite scattered clashes. The Syrian National Coalition said rebel factions would respect the cease-fire but retaliate if the government and its allies resumed shelling and airstrikes in rebel areas.
