Reuters is reporting that the US and Turkey are contemplating the establishment of "no fly zones" in Syria in order to assist the rebels:

"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," Clinton said.

Asked if such discussions included options such as imposing a no-fly zone over territory that Syrian rebels claim to control, Clinton indicated that was a possible option.

"The issues you posed within your question are exactly the ones the minister and I agreed need greater in-depth analysis," Clinton answered, although she indicated no decisions were necessarily imminent.

The imposition of no-fly zones by foreign powers were crucial in helping Libyan rebels overthrow Muammar Gaddafi last year. But until recently, the United States and its European allies have expressed reluctance to take on an overt military role in Syria's 17-month-old conflict.

The rebels are believed to be getting arms from Saudi Arabia and Qatar but only non-lethal assistance from the United States.

Davutoglu, responding to a similar question on next measures, said it was time for outside powers to take decisive steps to resolve the humanitarian crisis in cities such as Aleppo, which is under daily Syrian government bombardment.

This is a terrible idea. Syria has a sophisticated air defense network and would no doubt shoot down a few of our planes. This would necessitate a response that would probably include bombing the radar and command and control sites to ensure the safety of our aircraft.

That's war by any definition. And it is an escalation that might lead to a widening of the conflict:

Overnight Syrian and Jordanian forces clashed along the border in an incident that highlighted international concerns that the civil war in Syria could ignite a wider regional conflict. The clashes also emphasised the urgent need for planning on what could follow Assad's fall.

Syria and Turkey are also on a hair trigger and it wouldn't take much to expand the war there. Israel is very worried about Syria losing control of its WMD and have indicated that will go in to secure it if necessary. Iran has sworn not to allow Assad to fall, which could mean some kind of intervention on their part.

The dominoes are all lined up waiting for someone to push over the first one. A no fly zone might just start something that no one wants -- a regional conflict.
