The Pentagon has conceded that some elements of Pakistan's Inter-Services Intelligence are supporting the terrorist networks in the country, which is a matter of serious concern for the US.Interacting with reporters, Penatagon Spokesman Col David Lapan said some members of the ISI might be interacting with terrorist organisations in ways that aren't consistent with what the government and military are doing. He said this in response to questions about a news report in The Wall Street Journal which said that ISI is asking and assisting Taliban against NATO and US forces in Afghanistan. Noting that ISI as an organisation does not support terrorism, Lapan said some elements within the intelligence agency are providing assistance to terrorists. Observing that the top Pakistan military leadership is working to correct the problem, he said, but like any large organisation, change is difficult and comes slowly.
