EDISON - Local and national police forces are stepping up security following the death of Osama bin Laden in Pakistan.
The Port Authority of New York and New Jersey says it will station more officers at airports, bridges and at the World Trade Center site today.
Officials say the extra security is a precautionary measure and is not in response to any particular threat.
After bin Laden's death was announced, the State Department issued a worldwide travel alert, saying there is an "enhanced potential for anti-American violence."
