Islamabad , Pakistan ( CNN ) -- A Pakistani man is suing the U.S. government for $ 500 million over the death of his son and brother , whom he said were killed in a U.S. unmanned drone strike last year , his attorney said . Shahzad Akbar , attorney for Kareem Khan , said his client also wants all drone attacks halted . He said he has submitted a legal notice to U.S. officials , including Defense Secretary Robert Gates , CIA Director Leon Panetta and Islamabad 's CIA station chief . Kareem Khan said an airstrike on December 31 , 2009 , targeted his home in Machikhel , a village in North Waziristan . Khan , a 43-year-old journalist , said he was n't there at the time but that his family described a huge blast when the missiles hit . He said the reports that the strike killed militants were false . Instead , he says , the missiles killed his 35-year-old brother , Asif Iqbal , a teacher with a master 's degree in English literature , his 18 year-old son Zaneullah Khan , a staff member at a government school , and a construction worker who was working on a village mosque . Akbar said drone strikes are killing innocent civilians and also violating international law by ignoring the ban on targeted killings and assassinations away from a battlefield . Kareem argues that the CIA station chief is `` a murderer who is to be taken to task . '' Akbar said he is appealing to `` all those innocent victims/heirs of drone attacks to come and joins hands to get justice for their loved ones . '' Two intelligence officials told CNN this week that that Kareem Khan was housing Haji Omar Khan , a notorious Taliban commander who also was killed in the strike . Kareem Khan denied that he knew Haji Omar Khan . Khan said news reports on the attacks were `` mostly misreported . '' `` When my house was attacked , it flashed on the news that militants have been killed , '' Khan said . `` There were no militants in my house , neither on the day of drone strike nor before . My house was n't a training center , either . Only innocent people where killed . ''
