"We may suddenly arrive one night," Erdogan told reporters after a speech to parliament in Ankara on Tuesday, referring to a possible cross-border offensive in northeast Syria. "We have tried every means, with great patience, to solve this problem together with our allies... Turkey doesn't have a single day left to lose on this issue," Erdogan said.

The Turkish lira weakened on the news for the second day ahead of the possible cross border offensive, which would inevitably lead to direct clashes with US proxy forces in Syria's northeast, especially the Kurdish YPG arm of the Syrian Democratic Forces (SDF). 

Last week at the UN General Assembly President Erdogan presented his plan to set up a massive 300 mile long 'safe zone' along the border, which would be almost 20 miles deep into Syrian territory, where with international support Turkey would resettle up to 2 million refugees.
