India on Monday said the killing of Osama bin Laden was a "victorious milestone" in the war against terrorism even as it raised concerns about militants finding sanctuary in Pakistan, DPA reported.
Federal Home Minister Palaniappan Chidambaram said the US had informed India that the al-Qaeda leader had been killed by security forces somewhere "deep inside Pakistan" late Sunday.
"This fact underlines our concern that terrorists belonging to different organizations find sanctuary in Pakistan," Chidambaram said in a statement.
Indian leaders raised the subject of the 2008 Mumbai attack plotters still being in Pakistan.
"We believe that the perpetrators of the Mumbai terror attack, including the controllers and handlers of the terrorists who actually carried out the attack, continue to be sheltered in Pakistan," Chidambaram said, calling on Pakistan to arrest the suspects.
The attack, which has been dubbed India's 9/11, was carried out by the Pakistan-based group Lashkar-e-Taiba and led to the killing of 166 people including 26 foreign nationals.
Indian foreign minister SM Krishna said bin Laden's killing "is an historic development and a victorious milestone in the global war against the forces of terrorism."
"The world must not let down its united effort to overcome terrorism and eliminate the safe havens and sanctuaries that have been provided to terrorists in our own neighbourhood," Krishna said. "The struggle must continue unabated."
