American journalist Glenn Greenwald responsible for writing many of the stories about the NSA disclosed by Edward Snowden says he will now start publishing material more frequently.

 

　　The comments come a day after his partner David Miranda was detained for nine hours at London's Heathrow Airport.

 

　　Greenwald said he would be much more aggressive than before in his reporting.

 

　　"I will publish many more documents than before, I will publish many things on Britain as well, I have many documents on Britain's spying system. Now my focus will be that, they will regret what they have done."

 

　　Greenwald is now living with Miranda in Rio de Janeiro.

 

　　Miranda claims personal objects were taken from him when he was detained under anti-terror legislation.

 

　　Brazil's Foreign Minister Antonio Patriota says the detention is unjustifiable.

 

　　"We consider that this nine-hour detention is unjustifiable, based on legislation that applies to suspects involved in terrorism. We hope this will not happen again and today I will meet with Britain's Foreign Secretary William Hague to transmit this message."

 

　　Greenwald has written about NSA surveillance programs based on files disclosed by Snowden.

 

　　Snowden now has temporary asylum in Russia.
