A suicide bomber detonated an explosive device in the heart of the Turkish capital, Ankara, while a second assailant was killed in a shootout with police Sunday, the interior minister said.

The attack occurred hours before Turkey鈥檚 Parliament was set to reopen after its three-month summer recess with an address by .

Two police officers were slightly wounded in the bombing near an entrance to the Ministry of Interior Affairs, minister Ali Yerlikaya said on X, the social media platform formerly known as Twitter. Assailants who arrived at the scene inside a light commercial vehicle carried out the attack, he said.

鈥淥ur heroic police officers, through their intuition, resisted the terrorists as soon as they got out of the vehicle,鈥� Yerlikaya later told reporters. 鈥淥ne of them blew himself up, while the other one was shot in the head before he had a chance to blow himself up.鈥�

鈥淥ur fight against terrorism, their collaborators, the (drug) dealers, gangs and organized crime organizations will continue with determination,鈥� he said.

The interior minister did not say who was behind the attack. However, ANF 亚洲天堂, a news agency close to the banned , or PKK, reported Sunday night that the group had claimed responsibility for the blast.

Leftist extremists and the have also carried out throughout Turkey in the past.

Erdogan gave his speech in Parliament as planned and called the attack 鈥渢he last stand of terrorism.鈥�

鈥淭he scoundrels who targeted the peace and security of the citizens could not achieve their goals and they never will,鈥� he said.

The president reiterated his government鈥檚 aim to create a 30-kilometer (20 mile) safe zone along Turkey鈥檚 border with Syria to secure its southern border from attacks.

Turkey has launched several incursions into northern Syria since 2016 to drive away the Islamic State group and a Kurdish militia group, known by the initials YPG, and controls swaths of territory in the area.

Turkey views the YPG as an extension of the PKK, which is listed as a terror group by Turkey, the United States and the European Union. The PKK has waged an insurgency against Turkey since 1984. Tens of thousands of people have died in the conflict.

Last year, in Istanbul left six people dead, including two children. More than 80 others were wounded. Turkey blamed the attack on the PKK and the YPG.

The State-run Anadolu Agency reported that the two attackers on Sunday had seized the vehicle in the central province of Kayseri from a veterinarian. The pro-government daily Sabah reported that they shot the man in the head and threw his body into a ditch by the side of the road. They then drove the vehicle to Ankara, roughly 300 kilometers (200 miles) away.

Security camera footage on Sunday showed the 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.

Justice Minister Yilmaz Tunc said an investigation has been launched into the 鈥渢error attack.鈥�

鈥淭hese attacks will in no way hinder Turkey鈥檚 fight against terrorism,鈥� he wrote on X. 鈥淥ur fight against terrorism will continue with more determination.鈥�

Police cordoned off access to the city center and increased security measures, warning citizens that they would be conducting controlled explosions of suspicious packages.

The two police officers were being treated in a hospital and were not in serious condition, Yerlikaya said.

Egypt, which has normalized ties with Turkey after a decade of tensions, condemned the attack. A terse statement from the Foreign Ministry offered Egypt鈥檚 solidarity with Turkey.

The U.S. Embassy in Ankara and other foreign missions also issued messages condemning the attack.

Erdogan in his speech did not provide any indication as to when Turkey鈥檚 parliament may ratify Sweden鈥檚 membership in NATO.

While Finland has since joined, Turkey blocked Sweden鈥檚 membership in the military alliance, accusing it of not doing enough to tackle groups like PKK from operating on its soil. In a posting on X, Swedish Prime Minister Ulf Kristersson said Stockholm 鈥渟trongly condemns today鈥檚 terrorist attack in Ankara.鈥�

鈥淲e reaffirm our commitment to long-term cooperation with T眉rkiye in combating terrorism and wish for quick and full recovery of the ones injured,鈥� he wrote, using the Turkish government鈥檚 preferred spelling for the country.
