New Delhi, Mar 31: Prime Minister Manmohan Singh on Tuesday made it clear that composite dialogue with Pakistan could not be possible until Islamabad shows 
"visible results" with regard to investigation in the Mumbai terror attacks.

"They have to show visible results with regard to investigation in the 26/11 attack and that the government of Pakistan is doing everything possible to bring culprits to book," he said.

Singh was responding to a question on Pakistan President Asif Ali Zardari's emphasis on the need for early resumption of composite dialogue process.

The Prime Minister said Islamabad should convince New Delhi about their "sincerity and determination" to deal with the menace of terrorism.

On the terror strike on a police training centre in Lahore, the Prime Minister said India and Pakistan will have to jointly face the scourge of terrorism.

"I sincerely wish that the government and the people of Pakistan will have the courage and resources to defeat the forces of terrorism," the Prime Minister said on the sidelines of presentation of Padma Awards in Rashtrapati Bhawan.

Singh, who will be attending the G-20 summit in London, said terrorism will be a "major issue" during his talks with US President Barack Obama, whom he will meet for the first time on the sidelines of the summit on Thursday.

He said all bilateral and regional issues and India's relations with its neighbours besides the menace of terrorism will figure during the talks.
