With the violence in Syria getting worse, Foreign Affairs officials have renewed their call for Canadian citizens there to leave the country as soon as possible.

"Canadians may have little notice of violent outbreaks and risk being at the wrong place at the wrong time," officials say in an updated warning.

Leaving Syria by air could be difficult, officials say, because many airlines have suspended their flights to and from the country while there has also been violence near the airport in Damascus.
