UNITED NATIONS (AP) _ The U.N. General Assembly has endorsed without a vote an international convention against terrorism that obligates countries to extradite or prosecute terrorist bombers.

The convention defines a terrorist bomber as one who unlawfully and intentionally delivers, places, discharges or detonates an explosive device in a public place, government facility or public transportation system. The aim must be to cause death or serious injury, or destruction resulting in major economic loss.

The action took place Monday. The convention was one of dozens of resolutions approved without a vote as the General Assembly rushes to complete its work before the Christmas holidays.

The convention will be open for signature at U.N. headquarters from Jan. 12 to Dec. 31 and will take effect 30 days after the 22nd country ratifies it.
