Washington (Online) - The US has taken very seriously the reports about illegal modifications made in the American-made Harpoon anti-ship missile by Pakistan, to expand capabilities to strike land targets, even as Islamabad has agreed for mutual inspections. This is something that we take very seriously. We have raised the issue with the Pakistani Government. The Pakistani government has responded with an agreement in principle for mutually agreed inspections, the Assistant Secretary of State for Public Affairs P J Crowley, told PTI when asked about a news report published in The New York Times. In a news report published August 30, The New York Times, quoting unnamed American official, said the US has accused Pakistan of illegally modifications in the Harpoon anti-ship missile to expand its capacity to strike land targets.
