UPDATE 2-Turkey probes possible Syrian involvement in car bomb

* Car bomb near Syrian border killed nine people

* Turkey fears Syria conflict emboldening Kurdish militants

* Kurdish militants deny behind bombing

ISTANBUL, Aug 21 (Reuters) - Turkey is investigating

possible Syrian links to Monday's deadly car bomb attack near

its southeastern border, officials said on Tuesday, underscoring

fears that the conflict in Syria is fuelling instability on its

own territory.

A car packed with explosives blew up close to a police

station in the industrial city of Gaziantep, around 50 km (30

miles) from the Syrian border, late on Monday, killing nine

people including a 12-year-old child.

No group has claimed responsibility for the attack, but

senior ruling party officials in Turkey blamed the Kurdistan

Workers Party (PKK), Kurdish militants designated as a terrorist

group by Turkey, the United States and the European Union.

Turkey fears the PKK, which has waged an insurgency in the

southeast for almost three decades, is exploiting chaos in Syria

to expand its influence and has accused Syrian President Bashar

al-Assad of supplying it with arms.

Firat News, a website close to the PKK, carried a statement

from the group denying involvement in the attack, which took

place during the Eid al-Fitr festival marking the end of the

Muslim holy month of Ramadan. But security sources said they

believed Kurdish separatists were responsible.

"Another aim of this attack was to send a message about

Turkey's foreign policy. The attack was planned through the

cooperation of the Mukhabarat (Syrian intelligence) and the

PKK," Samil Tayyar, a member of parliament for Gaziantep from

Turkey's ruling AK Party, told reporters.

Foreign Minister Ahmet Davutoglu was more cautious, saying

that while possible Syrian links to Monday's attack were being

investigated, there was no concrete information so far.

"If there is a similarity, the methods and mentality of the

terrorist organisation and Bashar al-Assad's forces are alike in

killing civilians during Eid al-Fitr," he told reporters in

Ankara.

SUSPECTED SYRIAN LINKS

Ankara initially cultivated good relations with Assad's

administration but relations have deteriorated since the

uprising against him began 17 months ago.

Turkish Prime Minister Tayyip Erdogan has become one of

Assad's harshest critics and has raised the possibility of

military intervention in Syria if the PKK becomes a threat

there.

"It's known that the PKK works arm in arm with Syria's

intelligence organisation Al Mukhabarat. Assad is inclined to

view Turkey's foe, the PKK, as a friend," AK Party Deputy

Chairman Huseyin Celik told the Hurriyet newspaper.

In an interview with a Turkish newspaper at the start of

July, Assad denied that Syria had allowed the PKK to operate on

Syrian territory close to the Turkish frontier.

But Turkey suspects a major Syrian Kurdish movement, the

Democratic Union Party (PYD), of having links with the PKK.

Turkish analysts believe Assad let the PYD seize control of

security in some towns in northern Syria to prevent locals from

joining the rebel Free Syrian Army (FSA).

Turkish Deputy Prime Minister Besir Atalay told a news

conference that the target of Monday's attack had been the

police station and that the car carrying the bomb had been left

in place by a tow truck shortly before the explosion.

He declined to comment when asked about possible Syrian

involvement, saying the investigations was ongoing.

The attack came two days after Turkey began handing out food

and other humanitarian aid to Syrians fleeing the uprising

against Assad. Gaziantep is home to a centre that receives

international aid as Turkey struggles to cope with an influx of

almost 70,000 Syrian refugees.
