Barcelona plot fuels U.S. security concerns

WASHINGTON (Reuters) - The arrest of 14 people in Spain in a suspected Islamist bomb plot has fueled concerns over U.S. security as Bush administration officials are turning their attention to potential election-year threats, Attorney General Michael Mukasey said on Friday.

He said he could not discuss whether there was any U.S. connection in the suspected Barcelona plot, in which police raids last week uncovered explosives and other equipment.

"I just think when you get a plot of that kind exposed, as that one was, aimed at Western Europe or any place else it's a matter of concern. We know what happened last time," Mukasey told reporters. He cited earlier attacks in Spain, Britain and Bali, Indonesia.

In his first extensive meeting with reporters since taking office in November, Mukasey also said security officials were keenly aware of the potential for an al Qaeda strike timed around U.S. national elections November 4.

"I don't want to get into classified briefings, and that's going to get into it up to my hips," he said when asked about the election threat.

"Al Qaeda and other groups have shown that they want to act whenever they can act so as to have the greatest possible effect, by which is meant cause the most deaths and the most alarm and provoke the greatest level of uncertainty in the ability of democratic governments to survive," he said.

"I don't mean to suggest that there's anything specific going on now. It simply means that they're up to it all the time," he said.

Officials including Homeland Security Michael Chertoff have said the U.S. government is preparing for the possibility of an attack aimed at disrupting the election or transition to a new president. They say they know of no credible threats, but cite attacks in Madrid and London tied to political events.
