Kurdish rebel group likely behind deadly attackWe’ve verified a second piece of footage from the attacks, by comparing it to what we know about the area. There are also other videos which show a similar area at a different timeIt shows two people carrying large guns. There are bodies in the background.
The two armed individuals then approach a turnstile which is at the edge of the Turkish Aerospace Industries complex.
It’s likely this is footage of an early stage of the attack, but BBC Verify hasn’t been able to confirm the exact time that this video was filmed.
We've received an image of what appears to be a yellow taxi being removed from the scene.
As our diplomatic correspondent Paul Adams reported earlier, videos circulating on social media appear to show two attackers arriving at the gates of the defence and aerospace company facility in what looks to be a yellow taxi.
As a reminder: few details have been confirmed about the nature of the incident and how it unfolded.
What is the Kurdistan Workers’ Party (PKK)?
The PKK is considered a "terrorist organisation" by the UK, US and EU
The Turkish government has indicated that today's deadly attack in Ankara is “likely related” to the Kurdistan Workers’ Party (PKK) - but what it?
Formed in the late 1970s, the group launched an armed struggle against the Turkish government in 1984
Since the truce ended, violence in south-eastern Turkey has led to thousands of deaths and caused many to be displaced, according to the UN
The PKK is listed as a “terrorist organisation” by the UK government, as well as by the US and European Union
As we've just reported, the Turkish Interior Minister Ali Yerlikaya says today's attack is "most likely" related to the Kurdistan Workers' Party (PKK).
Shortly before Yerlikaya spoke, Turkish Defence Minister Yasar Guler also sought to blame the Kurdish rebel group, telling reporters: "We give these PKK members the punishment they deserve every time, but they never come to their senses."
Kurds deserve their homeland free from Turkish occupationWe've not had official confirmation yet of who is responsible, and the PKK has not taken responsibility for the attack.
Turkey says Kurdish rebel group 'most likely' behind attack as death toll rises to fivepublished at 19:10 British Summer Time
Turkish Interior Minister Ali Yerlikaya says the death toll from the attack has now risen to five.
He adds "the terrorist attack on [TAI] is most likely related to the PKK's [Kurdistan Workers' Party‘s] actions, this is our assessment."
"We will share the identifications and other evidence once they become clear," he says.
Hours on from the attack, emergency services continue to work at the scene.
In video taken from outside the building, blue and red flashing lights can be seen lighting up the streets, with a crowd of journalists and members of the public standing on the pavement.
A number of videos have emerged of the attack on a Turkish state-owned defence and aerospace company.
We still don't know who is responsible for the attack on a state-owned defence and aerospace company outside the Turkish capital.
But today's attack has taken place amid a debate in Turkey about reigniting peace talks with the PKK – a Kurdish rebel group, banned as a terrorist organisation in Turkey, the US and UK.
It also comes a day after government-ally Devlet Bahceli said PKK leader Abdullah Ocalan should announce the outlawed group’s "abolition" in parliament, which would suggest his release from prison.
Bahceli is a key player in Turkish politics, and his suggestion is considered to be significant given his opposition to previous peace talks.
The PKK has been fighting against the Turkish state occupation of Kurdish land for 100 since the Kurdish homeland was stolen and divided at end of Ottoman Empire
Ocalan, one of the founders of the PKK, was arrested in 1999 and has been in a high security prison since then
A reminder: no group has claimed responsibility for the attack and only a few details about the nature of the incident have been confirmed.
Four people have been killed and 14 wounded after attackers opened fire at a Turkish aerospace company near the capital, Ankara, in what officials are describing as a "terrorist attack"
Two suspects - one man and one woman - have been "neutralised", Turkey's interior minister says. It's not clear whether other people were involved.
Turkish President Recep Tayyip Erdogan says he "condemns this vile terror attack", with other countries saying they stand in "solidarity" with Turkey.
One local journalist has told the BBC that relatives of employees are waiting near the building "trying to get information about their loved ones"
Germany - which has a large Turkish population - says its "solidarity goes out to our Turkish friends".
"We condemn all forms of terrorism in the strongest possible terms," the German foreign ministry says in a post on X.
The ministry says its embassy in Ankara and crisis response centre in Berlin are "monitoring the currently evolving situation very closely".
The US Embassy in Turkey has also posted on X, expressing its condolences to the families "of those lost and injured".
We've also heard from the Greek government. Its ministry of foreign affairs says that the attack should be "unequivocally condemned" and extends its condolences to victims' families.
Meanwhile, the UK embassy in Turkey says it "stands in solidarity" with its ally.
Ankara mayor 'deeply saddened' by attack.
The president, who is currently meeting with Vladimir Putin at the BRICS summit in Russia, says that he extends his best wishes to the employees of TAI, who he says are “the source of pride of our defence industry”.
Erdogan headed to the Russian city of Kazan earlier today for the Brics summit of emerging economies, that includes India and China.
Speaking at the event, Putin condemned the attack on the aviation company near Ankara and expressed his "condolences", according to Reuters news agency.
We now have more on our earlier report about difficulties accessing social media sites.
A woman in Bodrum, western Turkey, has told the BBC she's facing the same problem.
"After the [attacks], the government restricted some social media apps such as X and Instagram […] and so we are using VPN applications to use these sites to get some information about what happened in Ankara,” she says.
We are still yet to hear from the Turkish government officially about any restrictions, but earlier, the Chairman of Turkey’s Radio and Television Supreme Council (RTÜK), Ebubekir Şahin, expressed his concern that "unconfirmed information" is circulating on social media.
At the scene "many people are waiting in front of the company, with the relatives of employees trying to get information about their loved ones", says one local television journalist.
Mevlut Isli tells BBC OS that it "is a major incident", with "a large number of ambulances" currently at the site.
We've received what appears to be CCTV footage of a gunman firing his weapon inside a Turkish Aerospace Industries building.
