Turkey said Thursday that all options are being considered in the fight against the Islamic State group after the foreign minister said Ankara was planning more military action against the jihadists soon.

"We have plans to act militarily against them in the coming days," Foreign Minister Feridun Sinirlioglu told a conference Wednesday in the northern Iraqi city of Arbil, describing IS as a "clear and present threat".

"You will see. We should all stand together against this danger," he said, according to the Anatolia news agency.

Sinirlioglu did not specify what sort of operation Ankara was planning or where.

Foreign ministry spokesman Tanju Bilgic said Thursday that Sinirlioglu did not specifically use the expression "ground operation", but added: "All options could be on the agenda."

Ankara has since July launched a number of air strikes against IS targets in Syria, although most of its firepower has been concentrated against Kurdish rebels in Iraq.

Turkey blames IS jihadists for the twin bombings last month on a peace rally in Ankara which killed 102 people and wounded 500 -- the deadliest attack in the country's history.

Police have also rounded up dozens of IS suspects in recent weeks in raids across the country.

Meanwhile, US President Barack Obama's deputy special envoy for the anti-IS coalition held closed-door talks in Ankara as part of a regional tour following talks in Vienna on the Syria conflict.

Obama and other world leaders will be in Turkey for a G20 summit on November 15-16 where the war is certain to be high on the agenda.

Turkey's NATO allies had long chastised Ankara for not taking a tougher line against IS as the extremists seized chunks of northern Iraq and Syria right up to the Turkish border.

Following months of Western pressure, Turkey became a full member of the US-led coalition against IS in August and now allows American jets to use its Incirlik air base for raids, potentially making it a more likely target for jihadist attacks.

Sinirlioglu said the threat from IS militants was "far from over".

"The occupation of one third of Iraq, and also vast areas of Syria, by Daesh has undoubtedly created one of the most serious challenges," he said, using another name for IS.

"Daesh continues to constitute a clear and present threat, aimed directly at our way of life, our security, prosperity and stability."
