India today said the killing of global terrorist Osama bin Laden was a matter of grave concern as it proved that terrorists belonging to different groups find sanctuary in Pakistan.
Union Home Minister P. Chidambaram said in a statement that perpetrators of the Mumbai terror attacks, including the controllers and handlers of the terrorists, continue to be sheltered in Pakistan.
He said that earlier today the US government informed New Delhi that Osama bin Laden had been killed by security forces somewhere "deep inside Pakistan."
"After the September 11, 2001 terror attack, the US had a reason to seek Osama bin Laden and bring him and his accomplices to justice," the statement said.
"We take note with grave concern that part of the statement in which President (Barack) Obama said that the fire fight in which Osama bin Laden was killed took place in Abbotabad 'deep inside Pakistan'.
"This fact underlines our concern that terrorists belonging to different organisations find sanctuary in Pakistan," he said.
The Home Minister said in the wake of this incident "we believe that perpetrators of the Mumbai terror attacks, including the controllers and handlers of the terrorists who actually carried out the attack, continue to be sheltered in Pakistan.
"We once again call upon the Government of Pakistan to arrest the persons whose names have been handed over to the Interior Minister of Pakistan as well as provide voice samples of certain persons who are suspected to be among the controllers and handlers of the terrorists."
