New York City went on a terror alert, reportedly prompted by a warning posted on an Israeli Web site.
Citing an “unverified” terrorist threat, the New York Police Department on Friday set up checkpoints in lower Manhattan and stepped up the deployment of radiological sensors on cars, boats and helicopters.
Reuters quoted a law-enforcement source as saying that the alert was prompted by DEBKAfile, a Web site that deals with security issues and is run out of Jerusalem. DEBKAfile had reported Internet chatter suggesting that al-Qaida would use trucks loaded with radioactive material to attack New York.
New York Mayor Michael Bloomberg described the alert as precautionary.
