Three suspected Islamic terrorists from an al-Qaida-influenced group nursing "profound hatred of U.S. citizens" were arrested on suspicious of plotting imminent, massive bomb attacks on U.S. facilities in Germany, prosecutors said Wednesday.

German Federal Prosecutor Monika Harms said the three, two of whom were German converts to Islam, had trained at camps in Pakistan run by the Islamic Jihad Union, a group based in Central Asia. They had obtained some 1,500 pounds of hydrogen peroxide for making explosives.

"We were able to succeed in recognizing and preventing the most serious and massive bombings," Harms told reporters.

Harms declined to name specific targets, but said the suspects had an eye on institutions and establishments frequented by Americans in Germany, including discos, pubs and airports.

Sudwestfunk televison, citing unnamed security sources in Berlin, reported that Frankfurt international airport and U.S. Ramstein Air Base were among the targets...

On Tuesday, Denmark's intelligence service said it thwarted a bomb plot and arrested eight Islamic militants with alleged links to senior al-Qaida terrorists.
