On the second anniversary of 26/11, India on Friday asked Pakistan to realise its "responsibility" to punish those behind the dastardly terror attacks with Prime Minister Manmohan Singh vowing to redouble efforts to bring the perpetrators to justice.
As the nation paid tributes to the 166 martyrs of Mumbai attacks, including 18 security personnel, India lamented that Pakistan had not punished the masterminds of the terror strike as it had promised.
To mark the occasion, Maharashtra Police took out a parade in south Mumbai beginning from Oberoi Trident Hotel, one of the sites of the deadly strikes.
Union Home Minister P Chidambaram and Maharashtra Chief Minister Prithviraj Chavan were among those who placed wreaths at the Police Gymkhana.
"I sincerely hope that on the second anniversary of this horrific tragedy, Pakistan will realise its responsibility as a nation, as a government and fulfil its promises to bring to justice those who perpetrated the attacks," said Chidambaram after attending commemoration events.
Recalling Pakistan's assurances, he said it had promised to bring to justice the masterminds, the controllers and the handlers of the terror strike by arresting all the seven persons whose names were handed over by India to it.
He said Pakistan had not even handed over the voice samples of the handlers of the 10 Pakistani terrorists who struck in Mumbai on this day two years back.
In a statement issued in Delhi, the Prime Minister said, "We pledge to redouble our efforts to bring the perpetrators of this crime against humanity to justice."
Asserting that India "will never succumb to the designs of our enemies," he said, "It is this spirit and strength of character of the Indian people that will defeat such forces that seek to threaten our social fabric and way of life".
Chidambaram said India has "learnt a lesson that while we will always trust our neighbour, we must always be on guard."
He was speaking after handing over the CNG filling station dealership to the family of Tukaram Ombale, an unarmed Mumbai police constable, who was killed when Kasab was caught alive in suburban Borivali on that fateful night two years ago.
"On a day like this while we honour those who laid down their lives, while we renew to our people our pledge that we will do everything in our power to secure this country and secure the people, it is my duty to caution the people that we have a neighbour who has not yet fulfilled the promises made to us," he said.
Chidambaram said there is a need to pay attention to proper training, weapons and housing needs of police forces.
"We must pay attention to police forces or else we won't have an efficient police. There are over three lakh
vacancies in police constabulary in India. We must pay attention to proper shoes, uniform, training, weapons, pay and housing needs of police force," Chidambaram said.
Lauding Ombale, who caught the lone surviving terrorist Ajmal Amir Kasab, he said, "If Kasab hadn't been caught alive, there would be no conclusive link to Pakistan in 26/11 attacks."
In Delhi, Parliament paid tributes to the martyrs and observed a minute's silence.
Defence Minister A K said the terror strike was "a grim reminder" of the volatile neighbourhood and expressed the nation's resolve not to allow a repeat of the 26/11-type mayhem in the country.
"It (Mumbai terror strike) is a grim reminder of the volatile and perilous state of our neighbourhood and thereby, the need for constant vigil," he said.
External Affairs Minister S M Krishna, who is in Colombo asked Pakistan to bring all the perpetrators of Mumbai attacks to speedy justice and dismantle the terror machine operating with "impunity".
He said the day was "a stark reminder, that no cause can ever justify terror, either by state or non-state actors."
In Mumbai, a parade was taken out wich saw participation of teams of Force One, Quick Response Teams (QRT) and Mumbai Police.
The parade, which began after Maharashtra Chief Minister Prithviraj Chavan took the salute, displayed advance anti-terror combat vehicles and weapons procured by the state police following the terror attack.
A 1.3-km long banner, which read 'The Great Wall of Mumbai', was held by hundreds of students from Mumbai starting from hotel Trident.
