Video footage has been released showing the moment two explosions hit a peaceful protest in the Turkish capital of Ankara, killing at least 86 people and injuring more than 100 others.

The mobile phone footage shows a long line of protesters by the city's central train station chanting whilst holding hands when an explosion occurs behind them, causing people to scream and run for cover.

The two explosions happened seconds apart shortly after 10:00am local time (8am BST), as hundreds gathered for planned peace march by the city's main train station. Protesters had been planning to hold a rally against the conflict between Turkish security forces and Kurdish militants in the south-east of the country.

Violence between the state and the Kurdistan Workers Party (PKK) militants has flared since July, when Turkey launched air strikes on militant camps in response to what it said were rising attacks on the security forces.

Designated a terrorist group by Turkey, the US and the EU, the PKK launched a separatist insurgency in 1984 in which more than 40,000 people have been killed.

Many Kurds want to establish their own homeland, linking up with Kurds in Turkey, Iraq and Syria. Recently a ceasefire between the Kurd groups and Turkish state broke down after two years, with Turkey bombing PKK positions and the PKK launching attacks on Turkish forces.

Turkish authorities have said that at least 86 people have been killed in the blasts with more than 100 injured. Authorities have labelled the explosions as a terror attack and are investigating claims that the blasts were carried out by suicide bombers, two government officials told Reuters.
