A resolution reached over Syria's chemical weapons has been hailed has a "breakthrough" by a senior US State Department official.
In a statement, the National Security Council said:
This is historic and unprecedented because it puts oversight of the Assad regime’s compliance under international control and it's the first UNSCR to declare that the use of chemical weapons is a threat to peace and security.
Equally as important, it makes absolutely clear that failure of the Assad regime to comply will have consequences.
