Three quarters of the most serious terrorist plots being investigated by the UK authorities are linked to Pakistan, British prime minister Gordon Brown said today.
Mr Brown said it was "time for action not words" in tackling the issue as he emerged from talks with Pakistani president Asif Ali Zardari.
Promising a £6 million "pact against terror", including anti-car bomb equipment and material to educate people out of becoming extremists, he said: "The aim must be to work together to do everything in our power to cut off terrorism."
Mr Brown, speaking at a joint press conference after the talks, also confirmed that he had told both the Pakistani and Indian leaders that British police may want to question the sole surviving gunman from the Mumbai massacre and other suspects from last month's atrocity in a bid to secure vital intelligence on extremist groups.
Mr Brown flew to Pakistan from New Delhi where he held talks with Prime Minister Manmohan Singh, amid mounting tensions between the neighbours over the Mumbai attacks, which killed at least 170 people including one Briton and two with joint British nationality.
India blames the outlawed Pakistani Islamist militant group Lashkar-e-Taiba for the attacks. Nine other gunmen were killed during the 60-hour siege.
Pakistani authorities began raiding and shutting offices and schools of the Jamaat-ud-Dawa charity, which is linked to the banned Lashkar, on Thursday. Scores of activists have been detained.
"We want to get more information on how Lashkar is working," the British source said.
India and Pakistan have fought three wars and went to the brink of a fourth in 2002 following an attack on the Indian parliament in December 2001 that New Delhi blamed on militants based in Pakistan.
