The U. N. Security Council on Wednesday urged countries around the world to implement a U.N. resolution aimed at keeping nuclear, chemical and biological weapons out of the hands of terrorists.

The council unanimously called for full implementation of an April 2004 resolution requiring all 192 U.N. member states to adopt laws to prevent “non-state actors” from acquiring weapons of mass destruction.

The council urged countries that haven`t filed a first report on their implementation efforts to do so “without delay.” It didn`t say how many countries have filed such reports or identify countries that have not done so.

The 2004 resolution, pushed by the United States, requires all countries to adopt laws to prevent non-state actors from manufacturing, acquiring or trafficking in nuclear, biological or chemical weapons, the materials to make them, and the missiles and other systems to deliver them.

It was introduced as the International Atomic Energy Agency was investigating a vast underworld market in nuclear equipment and know-how, spurred by Pakistan`s admission in 2004 that its leading nuclear scientist, Abdul Qadeer Khan, passed technology to Iran, Libya and North Korea.

U. S. Ambassador Susan Rice said the new resolution “sharpens the tools” of the Security Council committee that has been monitoring implementation of the 2004 resolution.

The White House said in a statement late Wednesday it applauded the committee`s new 10-year mandate and said it would contribute $3 million to help it achieve its goals.

“The continuation and enhancement of the (committee`s) work is an important element of the United States` nonproliferation objectives,” the statement said.

The committee has been helping countries to draft laws, ensure protection of material that could be used for weapons of mass destruction and prevent the export of any such material, and improve border security and law enforcement efforts.

The new resolution provides the committee with a group of eight experts, to be appointed by Secretary-General Ban Ki-moon, and additional technical assistance. It also extends the committee`s three-year mandate, which expires on April 25, for an additional 10 years until April 25, 2021.
