Iran has arrested four Iranians accused of involvement
in a U.S.-financed plot aimed at toppling its Islamic
system of government, the judiciary said Tuesday.
The announcement came a week before the inauguration
of Barack Obama as U.S. president. In a shift from George
W. Bush's approach, he has pledged to increase diplomatic
efforts to engage Iran and talk directly to its leaders.

Judiciary spokesman Alireza Jamshidi said the accused
were arrested in Tehran and their verdicts would be announced
soon.
