GUANTANAMO BAY , Cuba ( CNN ) -- Families of September 11 victims visiting Guantanamo Bay , Cuba , on Thursday urged the Obama administration to drop plans to close the facility and to restart terror trials there . A guard talks with a detainee at Guantanamo Bay , Cuba , earlier this year . `` I am opposed to the closing of this facility because of political reasons , '' said Gordon Haberman whose daughter , Andrea , was killed when terrorist planes struck the World Trade Center . `` I believe that the current administration spoke too quickly on this . '' Haberman said he thinks President Obama should not insist on carrying out his campaign pledge to shutter the detention facility . Haberman was one of nine people visiting Guantanamo this week who lost loved ones in the September 11 attacks . He and the others had the opportunity to observe pre-trial hearings for some suspects on Wednesday and Thursday . Several were critical of Obama 's decision to suspend military commissions at Guantanamo Bay while the administration reviews what to do with each detainee . `` Our government 's current executive order to halt the military commissions makes us foolish and weak , and invites more attacks , '' said Melissa Long , whose boyfriend was a first responder killed in New York . `` What is fair and just is to continue the military commissions and punish those who have committed acts of terrorism against Americans , period . '' Long later married a man who lost his parents when their plane slammed into the Pentagon on that fateful day . Brian Long acknowledged that some of the detainees may have gone through some inhumane treatment through the years , but he thinks they are being well taken care of now . `` The only injustice is being orchestrated by our leader by making decisions about something he knew nothing about , '' Long said . Other September 11 families have visited Guantanamo Bay for previous hearings and voiced support for using the facility for terror trials . The government uses a random process to select names of family members invited to observe . The family members said they think Guantanamo detainees have been provided with good attorneys , who , in many cases , are paired with clients who do n't want their help . Some of that was on display at a hearing Thursday for five detainees charged with orchestrating the September 11 attacks , including Khalid Sheik Mohammed . Mohammed and fellow prisoner Ramzi Binalshibh refused to come to the proceeding , after being told no detainees would be allowed to make statements . Three others did show up . But one , Mustafa al-Hawsawi , left quickly because he was not allowed to talk to the judge about problems he said he was having with one of his military lawyers . All five September 11 suspects want to act as their own attorneys . Thursday 's hearing focused on discussions about the competence of al-Hawsawi and Binalshibh to stand trial and represent themselves . Mohammed and two others have been granted permission to defend themselves .
Families of September 11 victims urge Obama to keep Guantanamo Bay open . They also want Obama to restart military commissions at all . Obama administration needs to determine what to do with detainees .
