The UK Prime Minister will pressure Turkey to exchange more information on Britons returning from the region who may have been fighting with Isis (Islamic State) militants.

David Cameron is to meet the nation's Prime Minister Ahmet Davutoglu and President Recep Tayyip Erdogan in Ankara, the Turkish capital.

The gathering will come after Federica Mogherini, European Union (EU) foreign affairs chief, met officials in Turkey to call for more action.

Downing Street said Cameron would concentrate on ongoing cooperation with Turkey, which neighbours Iraq and Syria, to stop Islamic State (IS).

"The primary subject area of discussion is going to be ongoing cooperation in the realm of counter-terror activity, in particular of course because of Isis," a spokesperson for the Prime Minister said.

The Prime Minister is also expected to ask the Turkish leader for more data on UK citizens travelling through the country to fight for Islamic-terrorist groups.

A report from the United Nations (UN) Security Council warned that the number of foreign fighters travelling to the conflicts in Iraq and Syria is at "an unprecedented scale".

The study found that 15,000 people have gone to Syria and Iraq to fight with IS and similar terror groups.

"There are instances of foreign terrorist fighters from France, the Russian Federation and the United Kingdom of Great Britain and Northern Ireland operating together," the report said.

Defence Secretary Michael Fallon said the government would commit to providing further support to forces fighting IS in Iraq earlier in the month.

Fallon announced that the UK would be increasing its current training offer to the Kurds, to include infantry skills such as sharp-shooting and first aid, alongside the provision of further equipment.

"Iraqi forces are spearheading efforts to push back Isis and their violent and repellent ideology," the defence secretary said.

"The UK, as part of the international coalition, is already taking part in air strikes across Iraq and carrying out training for Kurdish forces in the north of the country."

He added: "It is right that we do more to help Iraqi forces take the fight to ISIL on the ground which is why the UK is offering the further training, support and assistance I have outlined."

Fallon also explained that the UK was preparing to increase the number of Reaper remotely piloted aircraft in the region to provide further intelligence, surveillance and reconnaissance assistance to Iraqi forces in support of coalition and national interests.
