Over 40,000 security personnel have been deployed across Delhi to keep a hawk-eyed vigil against any possible terror strike.

The Udhampur attack, coming close on Gurdaspur’s heels, has shown that a plethora of Intel agencies working in J&K have lots to answer too.

"Ghulam Nabi Azad has strongly condemned the attack by Pakistani militants," a press release issued by his office said.

Two years after an explosion killed 17 persons outside the Delhi High Court, the NIA has charged a Pakistani national in the case.

The National Investigation Agency says there is a Pak hand behind the 2011 Delhi high court blasts that left 13 people dead.

Multiple blasts rocked Srinagar on Tuesday morning within a span of two hours from each other.
