Eight people, including children, have been hurt as rockets fired from Islamic State-controlled territory in Syria hit a Turkish border town.
The attacks on Kilis on Thursday were the first since Ankara-backed rebels swept into northern Syria last month to clear Sunni Islamist fighters from Turkey's southern border. That operation, dubbed "Euphrates Shield" by Turkey, was launched after months of attacks on Kilis reduced parts of the town to rubble.
"We entered Syria because these rockets are damaging property and human life. We want to establish security," Prime Minister Binali Yildirim told reporters in Ankara. He said six people, most of them children, were injured in the initial barrage.
The Turkish military said two rockets fired from an Islamic State-controlled region of Syria had hit the town in the first incident. The military said it tracked the origin of the rockets using radar and returned fire.
Around two hours later, another rocket hit Kilis and the military said it retaliated with air strikes. "Many Daesh targets were neutralised," it said in a statement, using an Arabic acronym for Islamic State.

Security sources said two more people were lightly injured in the second round of rocket fire.
At least six of the injured were Syrian nationals, Mayor Hasan Kara said. Kilis is home to many refugees from the Syrian civil war.
Cross-border rocket attacks have killed 21 people and wounded 80 in Kilis since January, security sources said.
President Tayyip Erdogan said this week the rebel alliance of Syrian Arabs and Turkmen fighting under the banner of the "Free Syrian Army" could extend their zone of control in northern Syria by pushing south and attacking the Islamic State-held town of al-Bab.
Turkey's "safe zone" in the region could eventually span an area of 5000 square km, from around 900 square km now, he said.
Turkey has long argued for a "safe zone" or "no-fly" zone along its Syrian border, with the aim of clearing out Islamic State and Kurdish fighters and stemming a wave of migration.
Western allies have so far balked at the idea, saying it would require a significant ground force and planes to patrol.
