1Two explosions at a road junction in the center of the Turkish capital Ankara have killed at least 86 people and injured nearly 200 others, the country's health minister said.

The first blast occurred at around 10:00am (0700 GMT), with the second following shortly after, during a peace rally organized by several leftist groups, including the pro-Kurdish Peoples' Democratic Party (HDP).

Authorities are exploring the possibility that the blasts may have been caused by two suicide bombers.

Prime Minister Ahmet Davutoglu announced three days of national mourning during a televised press conference on Saturday afternoon.

"We have to stand together against terrorism to defend our country," Davutoglu said, adding that the target of the attack was Turkish unity, democracy and stability.

"We are confident that there is no single citizen who doesn't share the deep sorrow for those who have lost their loved ones in these attacks."

No groups have claimed responsibility for the explosions.

A video on social media showed the moment of one explosion: young people were dancing and waving banners as a massive fireball erupts.

The explosions occurred near a train station where people were gathering for a peace march to protest against the conflict between the state and Kurdish fighters in southeast Turkey.

At a press conference in Ankara on Saturday afternoon, the Turkish health minister said that the death toll from the blasts had risen from 30 to 86, with 186 injured, including 28 who are in intensive care.

Video footage on social media showed several bodies lying on the ground, as survivors tried to attend to the wounded.
Faruk Bildirici, a Turkish journalist who was attending the rally, told Al Jazeera that he was only meters away from the blasts and there were only seconds between the two attacks.

Some people were crying and shouting out condemning the attack, some - particularly members of the Turkish Medical Association - were trying to help the wounded." he said.

"I have seen people using banners trying to cover dead bodies and striving to carry the wounded, again with large banners.

"This gathering was to deliver a message of peace, democracy and brotherhood in Turkey. This attack prevented people from delivering this message."

'Barbaric attack'

"We are faced with a huge massacre. A barbaric attack has been committed," said the HDP's leader Selahattin Demirtas.
Turkey's President Recep Tayyip Erdogan strongly denounced the attack.

"I strongly condemn this heinous attack on our unity and our country's peace," Erdogan said in a statement posted on the presidency's website.

"No matter what its origin, aim or name, we are against any form of terrorist act or terrorist organization. We are obliged to be against it together," Erdogan said.

The attack came with Turkey on edge ahead of November 1 polls and a wave of unrest over the past few months.

An attack in the predominantly Kurdish town of Suruc on July 20 targeting pro-HDP activists and blamed on ISIL fighters killed 32 people and wounded 100 others.
PKK ceasefire

Hours after the blasts in Ankara, the PKK called for a unilateral ceasefire in its fight against the Turkish state "unless they or the Kurdish people are attacked", according to a statement carried by Kurdish news agencies.

The statement was released by the Group of Communities in Kurdistan (KCK) and did not reference Saturday's attack in Ankara.

The move was widely expected as analysts said the PKK hoped it would boost the HDP's score in the upcoming election.
