The Turkish parliament approved a motion on Thursday enabling the government to authorize cross-border military incursions into Iraq and Syria to battle Islamic State militants.
The motion also allows foreign soldiers to be stationed in Turkey and to use its military bases for the same purposes.
Ankara has come under pressure to play a more robust role in the U.S.-led military campaign against Islamic State fighters after the insurgents advanced to within clear sight of Turkish military positions on the Syrian border.
More than 160,000 refugees have crossed into Turkey from the Kobani area since an IS offensive began in mid-September.
Turkey was already home to more than 1 million Syrians who fled the civil war in their country.
