The senior US official has refused to comment over the reports of American intelligence having evidence of ISI's involvement in last month's blast at Indian Embassy in Kabul saying it an issue of intelligence matters.
For past two days, there were reports that the US intelligence has seen evidence of ISI's involvement in bombing at Indian embassy in Kabul with a top CIA official even travelling to Pakistan to confront the matter of ISI-Taliban association.
"I saw that report. It would be inappropriate for me to talk about intelligence matters here, so I'd refer you to the intelligence community, if in fact they would like comment on it," White House Press Secretary Dana Perino said in Kennebunkport, Maine.
The senior White House official said during their meeting on Monday last, President George W Bush and Pakistan Premier Yousuf Raza Gilani had an extensive conversation about counter-terrorism efforts.
"They agreed that the war on terror was one that we needed to fight together because the enemy is going not just after Pakistanis, but the United States as well. And so our joint efforts need to be comprehensive," Perino said.
Soon after the bombing of the Indian mission in Kabul, in which two Indian Embassy officials were killed, Afghanistan blamed Pakistan for the attack and soon thereafter New Delhi also maintained that Islamabad may have been behind the incident.
