New Delhi, May 2 (IANS) Prime Minister Manmohan Singh Monday welcomed the killing of Al Qaeda leader Osama bin Laden ‘as a significant step forward’ and hoped it would ‘deal a decisive blow’ to terrorist groups.

He also said the international community and ‘Pakistan in particular’ must work to end the activities of terror groups.

‘I welcome it as a significant step forward and hope that it will deal a decisive blow to Al Qaeda and other terrorist groups,’ prime minister said in his message.

‘The international community and Pakistan in particular must work comprehensively to end the activities of all such groups who threaten civilized behaviour and kill innocent men, women and children,’ he added.

American military and CIA operatives cornered the world’s most wanted terrorist in Abbottabad, just 50 km northeast of Pakistan’s capital. The killing ended a 10-year manhunt for the Al Qaeda leader.
