A diplomatic incident...

That was almost bound to happen! Turkey shooting down a Russian military plane. Reality Check goes Live to Istanbul.

It's over 40 years since an incident like this has happened. A NATO member country shooting down a Russian military plane!

Turkish F-16 jets today shot down the aircraft after it violated Turkish airspace. Ankara said that the plane was given several warnings.

This obviously has caused a huge diplomatic incident although it should come as no surprise, as reported incursions into Turkish airspace were becoming more frequent . And Ankara had apparantly been warning Russia for weeks to steer clear of its air corridors, after several previous violations.

What challenges does this pose for the complicated relationship NATO and the West has with Moscow? We go to our correspondent Dorian Jones in Istanbul.

• ISIS and the money trail

Where does ISIS get its funding from primarily and how difficult is it to reduce or even stop its financial resources? We put that to our security analyst Shashank Joshi.

• Fostering refugee children

With more than 6,000 unaccompanied refugee children applying for asylum in Austria this year, a new project in Vienna aims to find foster parents for those children under the age of 14. We hear from Katharina Glawischnig from Asylkoordination, who set up the foster family project and is helping to coordinate it

• The route through Bulgaria

One so-called lower cost option for refugees (and one that avoids the Mediterranean crossing) is coming through Bulgaria. But this also has its own particular risks, as our Balkans correspondent Nick Thorpe tells us.

• Vatileaks

Five people go on trial in the Vatican today accused of leaking and publishing secret documents revealing corruption in the Holy See.

Two Italian journalists, Emiliano Fittipaldi and Gianluigi Nuzzi, cited the leaked documents in two books they wrote about financial mismanagement at the Vatican. They are the first journalists to stand before a papal tribunal. If convicted they would face jail sentences. But they would then be extradited to Italy, which does not jail journalists. So what is the vatican trying to achieve here? We go to Josephine Mckenna, our correspondent in Rome, for an update.
