Britan on Friday said there is clear evidence that the Mumbai terror attacks [Images] have links to Pakistan-based outfits.

Islamabad [Images] has been asked to take effective and appropriate measures against the organisations, British High Commissioner to India Sir Richard Stagg said in Chennai.

"We take the view that there is clear evidence that the attacks in Mumbai have links to organisations in Pakistan and we have been urging the Government of Pakistan to take effective and appropriate measures to deal with this," Stagg said.

Speaking to the media after visiting a Chennai municipal school imparting activity-based learning, Stagg termed the Mumbai attacks ghastly and appalling. It was an attack on India as a country, its values and people, he said.

The British envoy also lauded his national cricket team for deciding to resume their two-Test cricket match series with India.

Cancellation of the series for security reasons would have sent an unfortunate signal, he said. "Personally I am very delighted England [Images] is in Chennai at the moment. For, it would have been an unfortunate signal if they were unable to come due to security concerns. I am glad to know they have decided to donate half of their match fee for those affected in the Mumbai attacks. It is a strong and important signal," the envoy said.

On his country's advisory to British nationals touring India post 26/11 attacks, Stagg said: "We want to inform our people of the risk that exists and the nature of the threat and ask them to make their own judgments," he said. "It is not a criticism but we want to ensure our citizens are properly informed."
