The document stipulates that the folllowing terms be followed:

To fully implement UN Security Resolution 2254, adopted unanimously on December 18, 2015, including the readiness to participate in the UN-facilitated political negotiation process;

To cease attacks with any weapons, including aerial bombardments by the Air Force of the Syrian Arab Republic and the Aerospace Forces of the Russian Federation, against the armed opposition groups (as confirmed to the United States or the Russian Federation by parties to the cessation of hostilities);

To refrain from acquiring or seeking to acquire territory from other parties to the ceasefire;

To allow humanitarian agencies, rapid, unhindered and sustained access throughout areas under their operational control and allow immediate humanitarian assistance to reach all people in need;

To proportionate use of force (i.e., no greater than required to address an immediate threat) if and when responding in self-defense.

The development could pave the way for further talks and possibly a ceasefire between the rebels and the government of Syria, President Bashar al-Assad.
