The U-S spying scandal continues to cause outrage among Washington\'s allies. Now, Madrid has opened a preliminary inquiry into allegations the U-S spied on Spanish citizens. The prosecutor\'s office will investigate whether a crime was committed and if Spain should consider opening a formal investigation. The announcement comes a day after Spanish media published documents revealing that the U-S National Security Agency monitored over 60 million phone calls in the country within one month. Spain has warned that mutual trust between Madrid and Washington could be damaged if the allegations prove to be true. Spain is among several other countries who\'ve summoned U-S ambassadors to demand an explanation. European countries have also announced they will send a nine-member delegation to Washington to seek answers regarding the N-S-A\'s spying activities against European citizens and officials.
