UNITED NATIONS (AP) — Opening day at the United Nations’ annual gathering of world leaders saw beefed-up security measures and a suspicious package that added to the chaotic scene around U.N. headquarters in New York.

For the first time, apparently in response to escalating threats, U.N. security required all staff and lower-ranking diplomats to have their belongings scanned.

The problem was that there were only two scanners for hundreds and hundreds of people trying to get into the building via the staff entrance between 8 a.m. and 9 a.m. Tuesday, when the meeting started. Many faced long delays, and some were frantic.

Motorcades carrying presidents, prime ministers and monarchs to the building had priority on nearby streets and traffic was often at a standstill.

Meanwhile, First Avenue — which runs uptown alongside the U.N. complex — was closed to normal traffic. Only motorcades could enter. That meant that many vehicles trying to get uptown were using the closest uptown street —- Third Avenue.

Then police closed that, too — at midafternoon Tuesday after a report of a suspicious package — fouling up traffic for New Yorkers even more.

Police said they got a call around 3 p.m. Tuesday about a suspicious package near East 43rd Street and Third Avenue, prompting a response by bomb squad and other officers.

The object, police said, turned out to be harmless.
