Sirajuddin was found by American forces to be in the turbulent town during the recent audacious militant attacks on the Afghan capital Kabul.
This is for the first time that US officials have acknowledged tracing the Haqqani faction Taliban leader whose outfit they blame for the number of attacks on American establishments including the US embassy and NATO headquarters in Kabul.
US and Afghan officials have also blamed the recent attacks on western embassies and the Afghan parliament on the Haqqani network.
Quoting Pakistani officials New York Times reported that last week in Islamabad, American negotiators told their Pakistani counterparts they had located Sirajuddin Haqqani, the leader of the Haqqani network, in Miran Shah during the assault.
Washington has been pressing Islamabad to undertake a military offensive in North Waziristan where it believes that Haqqani network is based.
