Turkey's decision followed a deadly attack on Turkish troops by Syrian government forces in northern Syria this week.

Turkish President Erdogan says 18,000 migrants have crossed Turkish borders into Europe.
The number is expected to hit 25,000 to 30,000 in the coming days, he added.
Greece says it has blocked thousands of migrants from entering "illegally" from Turkey.
Greek authorities fired tear gas to attempt to disperse the crowds.
