Turkish PM blames Ankara bombing on IS
The Islamic State (IS) group is the prime suspect in the Ankara bombings that killed nearly 100 on Saturday, Turkish PM Ahmet Davutoglu has said.
No group has said it carried out the attack, but the government believes that two male suicide bombers caused the explosions.
The official death toll is 97, but one of the main groups at the march put the number of dead at 128.
The funerals of more of the victims are taking place on Monday.
Saturday's twin explosions ripped through a crowd of activists gathering outside the main railway station in the Turkish capital.
They were due to take part in a rally calling for an end to the violence between Turkish government forces and the militant Kurdistan Workers' Party (PKK).
Speaking on Turkish television, Davutoglu said the bombings were an attempt to influence the forthcoming elections, due to take place on 1 November after a vote in June left no party able to form a government.
Many of the victims were activists of the pro-Kurdish HDP party, which says it is now considering cancelling all election rallies.
The HDP believes its delegation at the march was specifically targeted.
The party gained parliamentary seats for the first time in June's vote, depriving President Recep Tayyip Erdogan's governing AK Party of its majority.
The attack is the most deadly in Turkey's history.
The situation in the country was tense even before the Ankara bombings: the ceasefire with the PKK had broken down and there had been clashes between the militants and security forces, killing at least 150 since July.
On Saturday the PKK unilaterally declared a new ceasefire. However, this was rejected by the Turkish government, which carried out cross-border air strikes on PKK positions in southern Turkey and Iraq on Sunday.
Davutoglu said authorities were close to identifying one of the suicide bombers, and that this would help to pinpoint which group carried out the attack.
He had previously said that IS, the PKK and far-left groups were all capable of such an attack.
Some local media have implicated the brother of a man who carried out an IS bombing in the southern border town of Suruc in July, which killed more than 30 people.
The BBC's Mark Lowen in Ankara says that critics of the Turkish government believe it is using IS as a scapegoat - and that murky elements of a so-called "deep state" are to blame for the bombings, aiming to shore up support ahead of the elections.
The leader of the HDP, Selahattin Demirtas, said the state had attacked the people - and that the people of Turkey should be the recipients of international condolences, not President Erdogan.
