A blast caused by a suicide car bombing hit the center of Ankara on Sunday evening. The explosion resulted in over a hundred casualties.

At least 34 people were killed and 125 injured in the explosion, according to the Turkish health ministry, as cited by Sputnik news agency.

The blast occurred near Guven Park in the city center.

The suicide car bomb went off at 6:43 pm local time (16:43 GMT), Turkish broadcaster TRT said.

The site of the blast is close to a courthouse and buildings housing the country’s justice and interior ministries.

What appears to be CCTV cam footage was posted on YouTube that allegedly shows the moment of the explosion. A couple of buses can be seen in the video, before a passing by car slows down near them and a huge blast is seen.

Turkish authorities have announced that they will release the name of the group responsible for the deadly blast and the results of the probe into the bombing on Monday. “I believe the investigation will be concluded tomorrow and the findings will be announced,” Efkan Ala said in comments broadcast live on local TV, as quoted by Reuters.

The blast was caused by "explosive-laden vehicle," according to Reuters citing Ankara governor's office.

The blast appears to have been triggered by a car exploding near a bus stop, TRT said. Guven Park adjoins a major transportation hub.

“It’s a car bomb, [it happened] in the heart of Ankara... and today is Sunday, many people may be outside,” Turkish journalist Onur Burcak Belli told RT by phone, adding that the scene of the blast is “very close to a shopping mall” and that “many cars are on fire and apparently a public bus is also on fire.”

“I was nearby when I heard the explosion, and there were casualties all around... the numbers of dead are increasing,” an eyewitness told RT by phone, adding that “the explosion was actually bigger than the last one in Ankara.”

No one has claimed responsibility for the attack so far.

A security official said that initial findings suggest the attack was carried out by Kurdish PKK fighters or a group affiliated with them, Reuters reported.

The pro-Kurdish Peoples’ Democratic Party (HDP) has issued a statement condemning the attack, saying it shares “the huge pain felt along with our citizens,” AP reported. The party has been previously accused of not speaking out against PKK violence.

Images allegedly showing the aftermath of the explosion emerged on social media. A huge fire could be seen in some of them.

A large cloud of smoke rising into the dark could also be seen from the distance.

Numerous loud sirens could be heard in a Periscope transmission from the scene, in which people can be seen running by, with some screaming.

Turkish President Recep Tayyip Erdogan pledged to bring “terrorism to its knees” following the bombing, avowing that the country would exercise its right to self-defense to avoid such attacks in the future.

“Our people should not worry, the struggle against terrorism will for certain end in success and terrorism will be brought to its knees,” Erdogan said.

The US and the EU, as well as NATO, have condemned the attack and conveyed their condolences to the families of the victims, while confirming their solidarity with Turkey in the fight against terror.

Russian Prime Minister Dmitry Medvedev has sent his sympathies “to the people of Turkey,” TASS agency reported.

“On behalf of the Russian Federation and on my behalf, I extend my condolences… to the close ones of those who died, and wish the speedy recovery to those injured,” Medvedev wrote.

The Australian ambassador to Turkey, James Larsen, was in his car 20 meters from site of the Ankara blast when the bomb went off, according to Australian Foreign Minister Julie Bishop.

“He is fine, obviously shaken by what he saw, we don’t believe there are any foreigners that have been killed or injured in the attack but investigations are still under way,” Bishop said, as cited by AAP.

In February, 28 people were killed and 61 injured in a blast in Ankara, when a car bomb, reportedly targeting military personnel, went off close to the parliament building. Forces linked to the Syrian Kurdish YPG militia were accused of committing that terrorist attack by Turkish Prime Minister Ahmet Davutoglu.

A splinter group of the outlawed Kurdistan Workers’ Party (PKK), the Kurdistan Freedom Hawks (TAK), later claimed responsibility, saying the bombing had been in retaliation for Turkey’s military operation in the country’s southeast and vowing to continue its attacks.
