UNITED NATIONS — The U.N. General Assembly overwhelmingly approved the first U.N. treaty regulating the multibillion-dollar international arms trade Tuesday, a goal sought for over a decade to try to keep illicit weapons out of the hands of terrorists, insurgent fighters and organized crime.

The resolution adopting the landmark treaty was approved by a vote of 154 to 3 with 23 abstentions. As the numbers appeared on the electronic board, loud cheers filled the assembly chamber.
