The U.S. State Department has warned of a threat of terrorist attacks on Americans attending holiday gatherings through January, possibly timed to coincide with Ramadan, which ends early next month. Citing “credible information,” the announcement advises travelers to avoid large gatherings and keep a low profile. Of biggest concern are New Year’s events in the Middle East, but the warning is not limited to the Middle East. The threat is believed to come from Osama bin Laden.
