LONDON (AFP) - The British and Turkish prime ministers held talks Tuesday on how to deal with the threat posed by Islamic State in Iraq and Syria (ISIS) militants.

It was the second meeting in just over a month between British Prime Minister David Cameron and his Turkish counterpart, Mr Ahmet Davutoglu, in London.

Turkey is a key entry route for Western volunteers travelling to join ISIS in Syria, where the group has carved out regions of control and brutally executed a series of hostages.

Mr Cameron's office said the two would work together on sharing passenger manifests on flights and plans for temporary exclusion orders to stop suspected extremists from returning to Britain.

"The battle that we have fighting extremist terror and the terrible situation we see with ISIL (ISIS) and also the need for transition in Syria" will be at the top of the agenda, Mr Cameron said.

"There's a lot that we have to work on."

The Turkish prime minister said there would be "strategic cooperation against any type of threat against international and regional peace" between the two countries.

"The future of our continent now faces many challenges: terrorism, racism, other types of challenges against our countries, Turkey and Britain. I'm sure will be shoulder to shoulder," Mr Davutoglu said.

The United States and the European Union have been pressuring Turkey to be more assertive in tackling ISIS on its long Syrian border.
