Bill Gertz passes along some scary news; an intelligence report that a group of Chechen terrorists entered the US through the Arizona-Mexico border: Chechen terrorists probed.

U.S. security officials are investigating a recent intelligence report that a group of 25 Chechen terrorists illegally entered the United States from Mexico in July.

The Chechen group is suspected of having links to Islamist terrorists seeking to separate the southern enclave of Chechnya from Russia, according to officials familiar with intelligence reports.

Members of the group, said to be wearing backpacks, secretly traveled to northern Mexico and crossed into a mountainous part of Arizona that is difficult for U.S. border security agents to monitor, said officials speaking on the condition of anonymity.
