Istanbul: Turkey`s leaders on Friday confirmed a landmark deal with the United States on the use of a key air base near Syria, after Washington said American jets would be able to use the facility to launch raids against jihadists.
Hurriyet daily said the agreement for US planes to use Incirlik base in southern Turkey provided for a 90-kilometre (56 mile) no-fly zone between the Syrian towns of Marea and Jarabulus to the east.
"It (Incirlik) will be used within a certain framework," President Recep Tayyip Erdogan told reporters in Istanbul, without giving further details.
Asked about the deal Prime Minister Ahmet Davutoglu said: "A decision has been taken for Turkey`s own security."
US officials had grown increasingly frustrated over Turkey`s reluctance to play a full role in the coalition against IS, including its refusal to let Incirlik be used for bombing raids against IS.
But a suicide bombing in a Turkish border town blamed on IS followed by border clashes appear to have hardened Ankara`s resolve.
Turkish warplanes on Friday for the first time bombed IS targets in Syria.
The agreement with the US, which follows months of negotiations, was reportedly finalised in telephone talks between Erdogan and US President Barack Obama earlier this week and then approved by the Turkish cabinet.
"We confirmed in our talks with Obama our commitment to... fight against Daesh," Erdogan said, using an Arabic acronym for IS.
"We said Daesh is a terror group and Turkey will protect itself against such a terror group," he added.
Hurriyet said the no-fly zone would shield a planned safe zone on the ground that would extend up to 50 kilometres (31 miles) inside Syria.
The safe zone would aim at preventing infiltration by IS and other jihadists thereby discouraging the flow of refugees to Turkey, it said.
Where necessary, US-led coalition forces could conduct reconnaissance and assault operations in the area, Hurriyet said.
"US planes equipped with bombs and missiles will be able to use the Incirlik Air Base" for raids against IS, the agreement says according to Hurriyet. Turkey could back up the air raids with artillery.
War planes from the regime of Syrian President Bashar al-Assad will not be able to enter the no-fly zone and will be targeted if they do so, it said.
The agreement does not foresee the arrival of any US ground troops in Turkey but an additional contingent of up to 50 US military staff will be allowed in for technical support.
About 1,500 US military currently serve at the base, which houses the US 39th Air Base Wing, the base`s website says.
The agreement only covers use of Incirlik, which is close to the city of Adana just east of the Syrian border.
But US warplanes will be able to use the Batman, Diyarbakir and Malatya air bases in eastern Turkey in the event of an emergency, Hurriyet said.
The government meanwhile released details of a new "physical security system" aimed at improving border security, including sections of wall, trenches and expanded patrols.
