Turkey's security forces reportedly thwarted what officials are calling a "terror attack" after a bomb exploded outside the police headquarters in the capital of Ankara. 

At about 9:30 a.m. local time, two assailants arrived in a commercial vehicle outside the front of the entrance gate of the General Directorate of Security of Turkey's Ministry of Internal Affairs and "carried out a bomb attack," Turkish Interior Minister Ali Yerlikaya wrote on X, formerly Twitter. 

"One of the terrorists blew himself up and the other terrorist was neutralized. During the fire, 2 of our police officers were slightly injured. I wish a speedy recovery to our heroes," Yerlikaya wrote. 

"Our heroic police officers, through their intuition, resisted the terrorists as soon as they got out of the vehicle," Yerlikaya later told reporters, according to The Associated Press. "One of them blew himself up while the other one was shot in the head before he had a chance to blow himself up."

"Our fight against terrorism, their collaborators, the (drug) dealers, gangs and organized crime organizations will continue with determination," he said.

The incident happened hours before Parliament was scheduled to reconvene nearby after its three-month summer recess with an address by President Recep Tayyip Erdogan.

Erdogan went on with his address as planned, telling Parliament hours later, "Terrorists trying to destroy peace and citizens’ security will never succeed," according to Al Jazeera. 

"Today’s terrorist act in Ankara, in which two criminals were neutralized thanks to timely intervention of police, is last flutters of terrorism," Erdogan said.

Turkish Justice Minister Yilmaz Tunc said an investigation has been launched into the "terror attack."

"These attacks will in no way hinder Turkey's fight against terrorism," he wrote on X. "Our fight against terrorism will continue with more determination."

Security camera footage on Sunday showed a vehicle stopping in front of the ministry, with a man exiting it and rushing toward the entrance of the building before blowing himself up. A second man is seen following him.

Earlier, television footage showed bomb squads working near a vehicle in the area, which is located near the Turkish Grand National Assembly and other government buildings. A rocket launcher could be seen lying near the vehicle.

Turkish authorities later imposed a temporary blackout on images from the scene, according to the AP. 

The interior minister did not say who was behind the attack and there was no immediate claim of responsibility. Kurdish and far-left militant groups as well as the Islamic State group have carried out deadly attacks throughout the country in the past.

ATTACK ON TURKISH-BACKED OPPOSITION FIGHTERS IN SYRIA KILLS 13 MILITANTS

Last year, a bomb blast in a bustling pedestrian street in Istanbul left six people dead, including two children. More than 80 others were wounded. Turkey blamed the attack on the outlawed Kurdistan Workers’ Party, or PKK, as well as Syrian Kurdish groups affiliated with it.

Erdogan’s speech is being closely watched for indications as to when Turkey’s parliament may ratify Sweden’s membership in NATO.

Stockholm applied for NATO membership alongside Finland following Russia’s invasion of Ukraine last year. While Finland has since joined, Turkey blocked Sweden’s membership in the military alliance, accusing it of being soft on groups that Turkey considers to be security threats. Only Turkey and Hungary are yet to ratify Swedish membership.

During his address, Erdogan said Sunday that Turkey "no longer expects anything from the European Union, which has kept us waiting at its door for 40 years," according to Barron's. 

"We have kept all the promises we have made to the EU, but they have kept almost none of theirs," he said. 

The remarks come after the European Court of Human Rights ruled last week that the rights of a Turkish teacher convicted of what prosecutors called terrorism offenses had been violated because the case was largely based on his use of a phone app. The court said its ruling could apply to thousands of people convicted following an attempted coup in Turkey in 2016 after the prosecution presented use of the ByLock encrypted messaging app as evidence of a crime.

Ankara has blamed the coup on the followers of U.S.-based cleric Fethullah Gulen, a former ally of Erdogan. Turkey has listed Gulen’s movement, known as FETO, as a terrorist organization. Gulen denies any involvement in the failed putsch.

The "decision of the ECHR was the straw that broke the camel's back," Erdogan reportedly said Sunday. "[Turkey] will not turn back in its fight against this band of traitors."

Oprah Winfrey and Meghan Markle are reportedly among those being considered to replace late Sen. Dianne Feinstein, D-Calif. 

Winfrey's name is among those being floated for the role, according to Newsmax and The Desert Sun, but the successful TV host-turned-billionaire book publisher and entrepreneur indicated as recently as in May that she "is not considering the seat should it become vacant," according to the Los Angeles Times. 

It was announced Friday that Feinstein died at age 90. All eyes have since turned to Democratic California Gov. Gavin Newsom, who will appoint someone to serve out the remaining 13 months of Feinstein's term. The two term governor, who attended the second GOP debate in Simi Valley last week on behalf of President Biden's re-election campaign to lead counter Republican messaging, has stated in the past he will appoint a Black woman to the Senate in the event of Feinstein's passing. 

Newsom reportedly has national ambitions of his own amid rumors of a potential 2028 presidential run. As recently as earlier last week, Newsom insisted he would not challenge Biden in 2024. Meanwhile, sources told The Daily Mail that the Duchess of Sussex's name has also been thrown in the ring as Feinstein's potential replacement. 

She and Prince Harry reside in Montecito, California. 

TRIBUTES POUR IN FOR SENATOR FEINSTEIN FOLLOWING DEATH AT 90: 'A POLITICAL PIONEER'

"Meghan is definitely a long-shot but in the craziness that is US politics these days it's not an impossibility. Crazier things have happened," a major Democratic donor told the Mail. 

Markle's name was reportedly considered for the U.S. Senate before the 2020 election when Biden chose Sen. Kamala Harris as his running mate. At that time, a senior Labour Party source told the Mail that Markle had been "networking among senior Democrats" on the venture of building a grassroots campaign eventually targeting a presidential bid of her own. 

Markle has grown a close friendship with Gloria Steinem. A friend fo Steinem's told the Mail, "Gloria has been introducing Meghan to pivotal people within the party."

"Meghan is interested in politics more than anything else. That's where she believes her power is, but she has had to focus on making money," the unnamed source is quoted to have said. 

Newsom has said he would avoid the field of candidates already campaigning for Feinstein's post, which will be on the ballot next year and includes Rep. Barbara Lee, one of the state's most prominent Black women currently serving in elected office. In the hours after Feinstein's death, Newsom quickly faced calls to honor his commitment to name a Black woman for the role, with some leaders calling on him specifically to name Lee to the post, a reminder of the fraught dynamic Newsom faces with a key Democratic constituency.

NEWSOM CLAIMS DESANTIS TOOK 'BAIT' IN AGREEING TO DEBATE 'GUY WHO ISN'T EVEN RUNNING FOR PRESIDENT'

For Newsom, any choice he makes risks alienating key allies at home, including those he would need for a future national campaign. Should he follow through on his pledge to avoid picking from those already running in the Senate primary, he could select a true caretaker who would be replaced by whomever voters select in next year's election. A handful of Black women in office have been floated as possibilities, including Secretary of State Shirley Weber and Los Angeles County Supervisor Holly Mitchell.

But Lee and others lashed out at Newsom earlier in the month after he indicated he would select a caretaker instead of picking from the current slate of candidates.

"The idea that a Black woman should be appointed only as a caretaker to simply check a box is insulting to countless Black women across this country who have carried the Democratic Party to victory election after election," Lee posted on X, formerly known as Twitter.

That was echoed by Aimee Allison, who founded She the People, a political advocacy network for women of color, who said, "Black women are not mere caretakers, but the voting and organizing center of the national Democratic Party."

Lee on Friday posted that Feinstein was "a champion for our state, and served as the voice of a political revolution for women." She did not address the open seat.
