New Delhi, Nov. 14 -- The Delhi Police on Thursday said DNA testing has confirmed that the man, who executed the blast in the white Hyundai i20 car outside Red Fort on Monday evening, was Umar Un Nabi, the 35-year-old doctor from Pulwama in Jammu and Kashmir, who worked in Haryana's Faridabad. The DNA samples were taken from a severed leg stuck between the car's accelerator and steering. Officials at a forensic science laboratory (FSL) verbally informed police about the finding, even as the complete DNA report was awaited. The DNA sample of Nabi's mother was collected in Pulwama and brought to Delhi. "We had recovered multiple body parts from the car and the blast site, apart from the premises of the nearby post, religious structures, and shops. One severed charred leg was found stuck between the steering and accelerator of the car. The FSL has confirmed that the DNA sample taken from that leg has matched the sample of Nabi's mother, who was taken into custody in Kashmir. Her sample was collected there, flown to Delhi, and handed over to the FSL for testing," said a police officer, who asked not to be named. Officials called the DNA matching a crucial piece of evidence in the blast probe, as it will help investigators link Nabi's direct role to the explosion and also establish it as a "heinous terror incident". Nabi worked as an assistant professor at Al Falah University in Faridabad. The Delhi Police on Tuesday said he was linked to Dr Muzammil Shakeel Ganaie and Dr Adeel Rather, who were arrested in Jammu and Kashmir last week and were accused of storing over 2,900 kgs of ammonium nitrate, detonators, timers, and assault rifles in Faridabad. Police said that Nabi bought the i20 car 11 days before the blast from a dealer in Faridabad. He was seen with the dealer and his associate, Amir Rashid. On October 30, after Ganaie's arrest, Nabi allegedly went into hiding. Police said that when the huge cache of explosive material was found on Sunday night, Nabi "panicked" and fled to Delhi with a detonator and other material. Another officer said CCTV footage showed Nabi travelling around Badarpur Border, Connaught Place, Turkman Gate, Sunehri Masjid area, and finally the Red Fort. "However, we could not surely say he had died because out of the 10 bodies, only eight could be identified, and two were just body parts. We detained Nabi's mother and her two brothers for questioning. They were also taken for DNA testing." The officer said Nabi was alone inside the car at the time of the blast. On Wednesday, Nabi's other car, a Red Ecosport, was found in Faridabad. Police said their probe showed it was used to carry ammonium nitrate. Nabi is suspected of having helped Ganaie by taking explosive material from his rented accommodation near the university and storing it. Secretary of state Marco Rubio on Thursday said that the US remains aware of the potential for a broader escalation of tensions between India and Pakistan after the bomb blast near Delhi's Red Fort three days earlier, even as he praised the Indian investigation into the attack. "We are aware of the potential that it has, and so we spoke about that a little bit today, the potential that it has to become something broader," he said on the sidelines of the G7 foreign ministers meeting in Canada. Rubio, who met with external affairs minister S Jaishankar and offered his condolences for the lives lost in Monday's terror attack, said they will wait to see what India's investigation reveals. "We have offered to help. but I think they are very capable in these investigations. They do not need our help," Rubio said. Rubio was responding to a query about the possibility of increased tensions between New Delhi and Islamabad in the aftermath of the attack. He praised India's "measured" and "cautious" approach to the investigation. Rubio said the blast was "clearly a terrorist attack". Rubio was involved in the backroom diplomacy between Washington, New Delhi, and Islamabad after India launched Operation Sindoor in retaliation for the Pahalgam attack in April. The US State Department listed the Resistance Front, the outfit that claimed responsibility for the Pahalgam attack, a terrorist entity in July. In a statement in July, Rubio had said the move demonstrated the Trump administration's commitment to protecting national security interests, countering terrorism, and enforcing his call for justice for the Pahalgam attack. On Monday, the US State Department's South and Central Asia Bureau condoled the lives lost in the Delhi terrorist attack. "Our hearts are with those affected by the terrible explosion in New Delhi. We continue to closely monitor the situation. Our sincere condolences to the families who lost their loved ones. Praying for the speedy recovery of those injured," it said in a statement on X. Newly appointed US ambassador to India Sergio Gor also issued a statement of condolences....
