WASHINGTON (AP) — Two lawmakers are angrily reacting to what they say is a lack of cooperation from a U.N. agency that may have sent computers and other technology to Iran and North Korea in possible violation of U.N. Security Council sanctions.

Reps. Ileana Ros-Lehtinen and Howard Berman sent a letter to Francis Gurry, director general of the U.N. World Intellectual Property Organization, saying they were outraged by his refusal to a State Department request for an independent investigation.
