Security forces carried out a controlled explosion at the Pulwama home of Dr Umar Nabi early on Friday. Officials said the house was blown up using an improvised explosive device (IED) as part of the investigation into this week’s Red Fort blast in Delhi.

The demolition took place during the late hours of Thursday and continued into Friday morning.

Investigators have connected the Hyundai i20 that exploded near the Red Fort on Monday, killing 13 people and injuring more than 20 others, to Dr Umar-un-Nabi, a doctor from Kashmir.
Police believe he was the one driving the car, though his exact role is still being checked.

Soon after the blast, Jammu and Kashmir Police launched overnight raids and arrested six people, including three members of Umar’s family.

Officials also said Umar had stayed in touch with two other Kashmiri doctors who were detained in the Faridabad terror module case, where officers had found 2,900 kg of explosives.

Umar’s identity was later confirmed after DNA samples from the blast site matched samples taken from his mother.

People in his area earlier knew Umar as a bright and focused doctor. Officials said that over the past two years, he had started showing a shift towards hard-line ideas.

They found he was active on several radical messaging groups on social media.

They also found that Umar, along with two others, Dr Muzammil Ahmad Ganaie and Dr Shaheen Shahid, used the Switzerland-based encrypted app Threema to plan and talk about their activities.

He had also created a small group on Signal with only a few people to handle other parts of the operation.

According to investigators, the group had gathered more than ₹26 lakh and handed it over to Umar to support their plans.

The money was reportedly used to buy nearly 26 quintals of NPK fertiliser, worth about ₹3 lakh, from suppliers in Gurugram, Nuh, and nearby areas.

NPK, when mixed with other chemicals, is commonly used in making IEDs.

Eight suspects planned multiple blasts

Sources told PTI that around eight suspects were preparing to split into pairs to carry out coordinated blasts in four different cities.

The investigation is still underway, and officials said more details will be shared as the probe moves forward.
