U.N. weapons inspectors arrived in Iraq today — the first inspectors to enter the country since 1998. On Wednesday, they will resume the search for weapons of mass destruction and any plans to produce them. An advance team has already made logistical arrangements for the inspectors. They return under the terms of U.N. resolution 1441 which obliquely threatens military action against Iraq if it does not reveal and dismantle banned weapons programs. The inspections are off to a fast start, getting underway in less than half the time allowed by resolution 1441. Michele Kelemen reports.
