MANAMA, Bahrain (AP) _ U.N. nuclear experts installed surveillance cameras at an engineering complex in Iraq as part of a stepped-up program to monitor that country's weapons production.

Speaking to reporters at the inspectors' regional headquarters in Bahrain, team leader Garry Dillon said they installed four cameras at Um al-Maariq engineering facility, about a 20-minute drive from Baghdad.

With the cameras, experts expect to know if Iraq tries to produce equipment at the plant that could be used to enrich uranium for nuclear weapons.

Work on the U.N. monitoring program speeded up after Iraq in November acknowledged a U.N. Security Council resolution on long-term weapons monitoring in the hope of a quick end to the U.N. oil and trade embargo imposed after its August 1990 invasion of Kuwait.

''Certainly on this mission, when we've asked to see a facility, when we've asked to see a piece of equipment, or when we've asked to see a person, they made arrangements for us to do that,'' Dillon said.

Dillon's team also tagged machinery and sought information from the Iraqis on a variety of topics. ''We had a very positive response,'' he said.

In all, a total of 23 facilities around the country will be equipped for monitoring to ensure that Iraq does not try to revive its nuclear arms program, Dillon said.

Horst Reeps, a German who recently led a team of chemical weapons experts to Iraq, told reporters that 250 pieces of equipment used to produce pesticides and pharmaceuticals were checked and tagged to make sure the Iraqis don't use them to produce chemical weapons.

Iraq was the first country since World War I known to have used internationally prohibited nerve gases in its 1980-88 war with Iran.

The U.S.-led coalition that drove the Iraqis from Kuwait destroyed a massive stock of chemical weapons, and since the war U.N. experts have been working to wipe them out.
