For years each Sept. 11 brought warnings of heightened terrorist threats on the grim anniversary. But, thankfully, not this year. US Attorney General Eric Holder said yesterday that there have been no credible threats of terrorism against the US for next week, reports Reuters. "We don't have any credible, specific allegations of activity or threats of any kind of activity on Sept. 11," said Holder. Nevertheless, he added: "We are being vigilant with regard to what is out there. We are prepared to respond to anything that we see."
