KABUL, Afghanistan-- The Afghan president's office says a man accused of plotting to kill President Hamid Karzai was not one of his personal bodyguards, as intelligence officials had initially said.

Karzai's office said Saturday the suspect was a member of the palace protection unit but that he was assigned to an outer gate of the presidential complex and had no access to the heavily secured palace.

Afghan intelligence officials announced Wednesday that they had broken up a cell that was planning to assassinate Karzai. They had said that a palace bodyguard from Karzai's hometown of Karz was among six people they arrested.

The others included a Kabul University professor and three college students. The officials said all had ties to militant groups.
