Pakistan's Prime Minister on Monday rejected the US President's allegations that Islamabad failed to cooperate with the US and had helped the former Al Qaeda leader Osama Bin Laden hide in the country until his death at the hands of the US military in a covert operation in 2011.

Imran Khan said in a series of tweets that Islamabad had joined the American war on terror even though no Pakistani national was involved in the 9/11 terror attack in the US, reports Efe news.
