Kurdish rebels attacked two military vehicles in southeast Turkey, the president said Sunday, indicating that several Turkish soldiers were killed. The prime minister was returning to the capital for a security meeting.

President Recep Tayyip Erdogan said in a television interview that two armored military vehicles were targeted by the Kurdistan Workers' Party near the village of Daglica, in Hakkari province, bordering Iraq and Iran. He indicated that several soldiers were killed in the attack.

Prime Minister Ahmet Davutoglu cut short a visit to the city of Konya to convene a security meeting. The state-run Anadolu Agency said the military had retaliated by launching an air operation.

"It was attack on armored vehicles with land mines," Erdogan said. "The information from our Chief of General Staff is very saddening."

He said Turkey's security forces would respond in a "different and determined" manner.

The renewed fighting between the PKK and the security forces has killed about 200 people since July, including around 70 soldiers and police officers. The fighting has derailed a 2 1/2-year-old peace process with the Kurds.
