Turning to Tehran

In what could mark an escalation of an already tense situation with Iran, top aides to President Bush met today to discuss options. Defense Secretary Donald Rumsfeld has said he's certain Tehran is harboring senior al-Qaida terrorists, a charge Iran denies.

Rumsfeld's remarks were the latest in a round of tough statements by American officials on what the United States alleges are Iran's supports for terrorism, weapons of mass destruction, relationship with al Qaeda and designs on Iraq.
