Talks between Pakistan's top intelligence agency Inter-Services Intelligence (ISI) and Britain's security officials have been cancelled after British Prime Minister David Cameron accused Pakistan of 'exporting terrorism'.

ISI called off the planned talks protesting Cameron's comments that elements within Pakistan are responsible for exporting terrorism abroad, an ISI spokesman said late Friday.

'The visit has been cancelled in reaction to the comments made by the British prime minister against Pakistan,' the spokesman was quoted as saying by the Guardian.

'Such irresponsible statements could affect our co-operation with Britain.'

Cameron's comments came Wednesday during his visit to India.

'We cannot tolerate in any sense the idea that this country is allowed to look both ways and is able, in any way, to promote the export of terror, whether to India, whether to Afghanistan, or to anywhere else in the world,' the British prime minister said.

British officials, however, said a visit by Pakistan President Asif Ali Zardari would still take place. Zardari is expected to stay with Cameron at his country residence.

'Our understanding is that the visit is on,' a foreign office spokeswoman said.
