The historic Red Fort in the crowded Old Delhi quarter of the city is one of India’s most well-known landmarks, and the site of the annual Prime Minister’s Independence Day speech.
The Cabinet expressed “profound grief” over the loss of lives.
It did not give further details of who might have been behind the attack, but said India would maintain a policy of “zero tolerance towards terrorism in all its forms”.
It condemned what it called a “dastardly and cowardly act that has led to the loss of innocent lives”.
Car exploded in traffic
Ritu Saxena, the chief medical officer of Delhi’s LNJP hospital, said that “12 people have died and more than 30 are injured”.
Witnesses described how the car exploded in traffic and how people caught up in the surge of flames were set on fire.
The explosion came hours after Indian police said they had arrested a gang and seized explosive materials and assault rifles.
Police said the men were linked with Jaish-e-Mohammed, a Pakistan-based Islamist group, and Ansar Ghazwat-ul-Hind, a Kashmir offshoot of the jihadist group Al-Qaeda.
Both groups are listed as terrorist organisations in India.
The government ordered an investigation with the “utmost urgency” so that “the perpetrators, their collaborators, and their sponsors are identified and brought to justice without delay”.
India’s National Investigation Agency is leading the probe into the explosion.
The government added India’s “steadfast resolve to safeguard the lives” of all its citizens, consistent with “its enduring commitment to national security”.
It also thanked foreign governments for messages of solidarity.
In the attack in April in Pahalgam, Indian authorities were swift to accuse Pakistan of backing the gunmen – claims denied by Islamabad.
That attack sparked clashes between the nuclear-armed arch-rivals in May, when more than 70 people were killed in missile, drone and artillery exchanges before a ceasefire was struck.
Also this week, after a suicide bomber in Islamabad killed at least 12 people, Pakistan’s Prime Minister Shehbaz Sharif blamed “terrorist proxies backed by India”.
India rejected the “baseless and unfounded” allegations made by an “obviously delirious Pakistani leadership”.
The Islamabad attack was later claimed by a faction of the Pakistani Taliban.
