Turkey’s military and Islamic State fighters have exchanged fire over the Syrian-Turkish border, killing one soldier, officials say.
The governor of Kilis province said another two soldiers were injured when a border post was attacked from Syria.
Turkey responded with heavy weapons, killing one IS militant, the army said.
It is the latest violence to hit Kurdish-dominated south-east Turkey, three days after 32 people were killed by a bomber linked to IS in Suruc.
Turkish officials have blamed the Suruc attack on IS.
The PKK added the Celanpinar attack was revenge for the Suruc killings, claiming the policemen had collaborated with IS.
Many in Turkey feel the government in Ankara has not done enough to support the Kurds in their fight to combat the threat of IS militants across the border in Syria – something denied by the authorities.
‘Tank fire’
“Unfortunately, one of our non-commissioned officers has been martyred and two sergeants injured,” Kilis Governor Suleyman Tapsiz told Turkey’s Anadolu news agency.
He added that the two wounded soldiers were in a stable condition.
In response, Turkish tanks opened fire on IS-controlled targets inside Syria, the Turkish army said.
It added that one IS militant was killed.
The latest attacks have added to the bloodshed in the area of Turkey nearest to IS-held territory.
On Monday, a suicide blast killed 32 people and injured another 100 in the mainly Kurdish town of Suruc, near the Syrian border. It was one of the deadliest attacks in Turkey in recent years.
A 20-year-old Turkish student has been identified as the suicide bomber.
The attacker, named by local media as Seyh Abdurrahman Alagoz, was an ethnic Kurd from Turkey’s south-eastern province of Adiyaman and reportedly had links to IS militants.
Alagoz’s mother told the newspaper Radikal (in Turkish) that her son was a former student at Adiyaman university who had gone “abroad” six months ago with his brother.
“I don’t know what they were doing abroad, they never said. They were just telling me they were fine,” Semure Alagoz said.
