WASHINGTON: The United States imposed sanctions on six men linked to the Afghan Taliban and the related Haqqani network on Thursday, less than a month after President Donald Trump ordered big cuts in security aid to Pakistan over its failure to crack down on militants. The counter terrorism designations announced by the US Treasury Department bars the two Pakistanis and four Afghans living in Pakistan from accessing the US financial system. In a surprise tweet on New Year?s Day, Trump said the United States had "foolishly" given Pakistan more than $33 billion in aid and "they have given us nothing but lies and deceit, thinking our leaders as fools. They give safe haven to the terrorists we hunt in Afghanistan, with little help. No more!" The announcement sent US officials scrambling to suspend security assistance, later estimated at up to about $2 billion, to the nuclear-armed ally. Pakistani officials were infuriated by the action. Its National Security Committee of senior civilian and military chiefs denounced it as "completely incomprehensible." The US Ambassador David Hale was summoned to the foreign ministry for an explanation. Pakistan is a crucial gateway for US military supplies destined for US and other troops fighting a 16-year-old war in neighbouring, landlocked Afghanistan.
