Washington - Turkey does not place a high priority on fighting Islamic State jihadists and as a result foreign fighters are able to travel through the country into Syria, US intelligence chief James Clapper said on Thursday.
Asked if he was optimistic that Turkey would take a more active role in the war against the ISIS group, Clapper told senators: "No, I'm not."
"I think Turkey has other priorities and other interests," he told the Senate Armed Services Committee.
The Turkish government was more concerned with Kurdish opposition and the country's economy, the director of national intelligence said.
"Public opinion polls show in Turkey they don't see ISIL as a primary threat," said Clapper, using an alternative acronym for the extremists.

The effect of Turkey's approach was to allow a "permissive" climate for foreign recruits heading to Syria to take arms for the ISIS group, he said.
"And of course, the consequence of that is a permissive environment... because of their laws and the ability of people to travel through Turkey en route to Syria," Clapper said.
"So somewhere in the neighbourhood of 60% of those foreign fighters find their way to Syria through Turkey."
The spy chief said some other governments in the Middle East have been reluctant to join the US-led coalition against the ISIS group because of Washington's reluctance to directly confront the Syrian President Bashar Assad's regime.
But the "brutal savagery" of the ISIS militants, including the beheadings of hostages and the immolation of a captured Jordanian fighter pilot, "have had a galvanising effect on opinion in the Mideast region," he said.
There was more willingness to cooperate with the United States in the war effort, with some countries now sharing intelligence with Washington, he said.
