The United States and Turkey have been considering the imposition of a no-fly zone over Syria as US Secretary of State Hillary Clinton met with  the Turkish foreign minister, Ahmet Davutoglu this week.

Announcing that a working group to help provide “very intensive operational planning" was being set up, Clinton said,

"It is one thing to talk about all kinds of potential actions, but you cannot make reasoned decisions without doing intense analysis and operational planning,"

"Our intelligence services, our military have very important responsibilities and roles to play so we are going to be setting up a working group to do exactly that."

Along with exploring the possibility of introducing a no-fly zone over the country, Clinton also mentioned that the group would examine steps that needed to be taken incase "the horrible event that chemical weapons (are) used".

She went on to say,

"What would that mean in terms of response, humanitarian and medical emergency assistance and, of course, what needs to be done to secure those stocks from ever being used or falling into the wrong hands?"

Recently, John Brennan, President Obama's senior counter-terrorism adviser, also said that nothing was "off the table."

Her comments come as the Syrian government continues to bombard the city of Aleppo and clashes between Jordanian troops and Syrian forces have been reported.
