ALEXANDRIA — A Moroccan-born man charged with plotting a suicide bombing inside the U.S. Capitol has waived his rights to preliminary and detention hearings.

Amine El Khalifi was arrested Friday and charged with attempting to use a weapon of mass destruction. This afternoon, he was ordered held pending indictment.

Authorities say the 29-year-old discussed plans to attack a Virginia office building and a synagogue with an undercover FBI operative he thought was a member of al-Qaida.

Later, El Khalifi allegedly volunteered to wear a suicide vest and to kill himself in a martyrdom operation at the Capitol. His arrest came after a lengthy FBI investigation.

Court documents say El Khalifi had been living illegally in the U.S. for more than a decade.
