WASHINGTON - The United States on Monday said the PML-N party's withdrawal from Pakistan's governing coalition would not affect the ongoing efforts to combat terrorism. "That is very much an internal Pakistan matter. I don't anticipate it would have any impact on our joint efforts to combat extremism," State Department spokesman Robert Wood said. He was asked to comment on the political crisis in Pakistan following PML-N decision to leave the PPP-led ruling coalition over different on the restoration of the judges deposed by President Pervez Musharraf when he imposed a State of Emergency last November. The spokesman also described the issues related to judges as internal matter for Pakistanis to resolve in accordance with their Constitution.
