US authorities say they are assessing the credibility of information they received on a possible al-Qaeda terror attack on the eve of election day. http://www.bbc.com/news/election-us-2016-37877391

New York, Texas and Virginia are believed to be the potential targets mentioned but a police spokesman said the information “lacks specificity”.

Officials say they regularly assess all possible threats before major events.

Voters go to the polls on Tuesday to decide whether Donald Trump or Hillary Clinton will be the next president.

The FBI said that it was working closely with law enforcement agencies and sharing intelligence reports.

A spokesman for the Port Authority of New York, which operates airports, tunnels and bridges around in the city, said it was “continuing with the high level of patrols” it already had in place.

The city is also hosting the annual New York City Marathon on Sunday which could be a target.
