Turkey Launches Air Strikes, Ground Operations Against ISIS in Syria

Istanbul: Turkey's army backed by international coalition air strikes launched an operation involving fighter jets and elite ground troops to drive Islamic State jihadists out of a key Syrian border town.

The operation, the most ambitious launched by Turkey in Syria conflict, is aimed at clearing jihadists from the town of Jarabulus which lies directly opposite the Turkish town of Karakamis, the prime minister's office said.

The operation began around 4:00 am local time (0100 GMT) with Turkish artillery pounding dozens of IS targets around Jarabulus.

Turkish F-16 fighter jets and coalition war planes also hit targets inside Syria. Media said an unspecified number of elite Turkish special forces were already on the ground inside Syria.

Tensions had flared across the Syria-Turkey border the previous day, following rocket fire from Jarabulus which landed inside Turkey with the Turkish army firing howitzer rounds in response.

"The Turkish Armed Forces and the International Coalition Air Forces have launched a military operation aimed at clearing the district of Jarabulus of the province of Aleppo from the terrorist organisation Daesh," the prime minister's statement said, using an Arabic acronym for the IS group.

The operation also appeared aimed at pre-empting any assault by Jarabulus by pro-Kurdish militias who also oppose IS but Turkey accuses of seeking to carve out a Kurdish region in northern Syria.

In an earlier interview with private NTV television, Deputy Prime Minister Numan Kurtulmus said Ankara saw Jarabulus -- "as a national security matter".

"What we have said, since the beginning, is that having Jarabulus or any other city held by IS is unacceptable," he said.

Turkey will want to show with the operation that it is serious about taking on IS, which has been blamed for a string of attacks inside the country, the latest a weekend attack on a Kurdish wedding in Gaziantep that left 54 dead.

Ankara was long accused of turning a blind eye to the rise of IS in Syria and even aiding its movements to-and-fro across the border, claims the government had always vehemently denied.

The launch of the operation comes the day US Vice President Joe Biden is due in Ankara to meet Turkey's leadership, with agreeing a unified strategy on Syria set to be a crucial issue.
