Turkish air force jets have attacked Islamic State targets across the border in Syria as 5,000 anti-terror police also raided addresses in Istanbul.
Three F-16 jets bombed Islamic State targets in the second day of fighting between the country and the terror group.
Tensions between the two have increased markedly over the past few days after IS militants fired at a Turkish military position on Thursday, killing a soldier.
A government statement said the air raids, which used laser-guided bombs to destroy three targets, were in response to that attack.
They were launched from inside Turkish territory and Syrian airspace was not violated, said a government official.
Turkey this week finally agreed to let the US military use the Incirlik air base near the Syrian border to launch its own attacks on IS, following months of negotiations between the two countries.
The move will make it far quicker for American planes to get into Syrian airspace and attack the group.
A massive police operation in Istanbul involving 5,000 officers also took place overnight.
It targeted suspected IS and Kurdish militant addresses in 26 areas of the city.
