Ankara explosion: Blasts hit rally in Turkish capital.
Two explosions have hit a peace rally in the Turkish capital Ankara, causing multiple casualties, reports say.
Turkish news agency Dogan said that at least 20 people have been killed. TV footage shows scenes of panic and people lying on the ground covered in blood, amid protest banners.
The blasts took place near the city's central train station.
The target appears to have been a march calling for an end to the violence with the Kurdish separatist group, the PKK.
Prime Minister Ahmet Davutoglu is being briefed by the interior and health ministers, state news agency Anadolu says.
Government officials say the blasts were a terrorist attack and are investigating reports that a suicide bomber was behind at least one of the explosions.
The leader of the pro-Kurdish HDP party has blamed the state for the attack, and cancelled all election rallies.
The HDP was among those calling for Saturday's rally for "peace and democracy", which was due to start at 12:00 local time.
The party tweeted that there were "numerous dead and injured", and that police "attacked" people carrying the injured away.
Local resident Emre told the BBC that he heard two separate explosions and saw a number of dead bodies. Angry people tried to attack police cars, he said.
An HDP rally in the city of Diyarbakir was bombed in June, ahead of general elections.
Turkey is holding another election next month, and the BBC's Mark Lowen in Istanbul says it was feared that another similar attack was imminent.

The ministry said at least 126 people had been wounded. The cause of the blasts was not immediately clear, but the semiofficial Anadolu news agency, citing local sources, said suicide bombers were thought to have been responsible.
A Turkish official reached by telephone said the incident was being investigated.

The explosion took place before a planned demonstration against the conflict between Kurdish militants and the government in Turkey’s southeast. Television footage showed several bodies scattered in the road and people tending to the wounded.
