United States Ambassador to Pakistan Cameron Munter on Monday said Mansoor Ijaz’s recent allegations were nothing but “a pile of lies”. According to a private TV channel, Munter rejected Ijaz’s statement regarding the “memogate” scandal and the Osama Bin Laden raid in Abbottabad as baseless and fabricated. Munter said the US was probing the NATO airstrikes on Pakistani checkposts, adding that Pakistan would be kept informed of the outcome. The US ambassador also promised that Washington would take action against those responsible for the strike. He said Washington was doing its best to comply with Pakistan’s demand of vacating the Shamsi airbase in time.
