At least five people have been killed in a large explosion at the Güvenpark Monument at the centre of the Turkish capital, Ankara, at 6.41pm (4.41pm GMT). The explosion's location is close to several government ministries.

The Turkish news agency Dogan has said that at least five people are known to have died, while early pictures and video from the scene show cars alight, a bus destroyed and a huge response from emergency services. The source of the explosion is currently unclear.

The following video claims to show the explosion, but it has yet to be verified.

This is the third explosion in Ankara since October. Last month, a Kurdish militant group took responsibility for an attack on a military convoy in the city which killed 28 people, and in October, 103 people were killed with 250 wounded after two suicide bombers detonated themselves at a peace rally.
