No evidence has been found linking a foreign government to a former U.S. soldier indicted for allegedly plotting to kill President Bush and other top officials, the U.S. attorney for New Jersey said.

U.S. Attorney Michael Chertoff said it does not appear Jamal Mohammed Warrayat, a naturalized U.S. citizen born in Kuwait, had outside help in the alleged plot to kill Bush, Secretary of State James A. Baker III, unspecified members of Congress and to attack military installations in three states.Warrayat, 32, was indicted Thursday on three felony charges. He could be sentenced to 15 years and fined $750,000 if convicted on all counts.

Warrayat has been held without bail since his Nov. 27 arrest. An arraignment is expected within two weeks.

Court papers said Warrayat wanted to kill the officials because they were against the interests of his group, but the papers did not describe the group or its interests further, and prosecutors would not elaborate.

According to the court papers, Warrayat told an undercover FBI agent that his group was ready to attack Bush and the others, as well as attack unspecified military installations in North Carolina, Texas and Kansas. He allegedly said the group was looking for help obtaining explosives, money and technical training.

Warrayat's attorney, Terence Scott, was not available for comment Thursday, his secretary said.

Scott has previously said Warrayat was born in Kuwait, came to the United States in the early 1970s and served about four years in the Army until 1979.
