Iraqi officials said Thursday that multinational forces detained five Iranians in a pre-dawn raid of Teheran's diplomatic mission in the northern city of Irbil. The forces stormed the building at about 3 a.m., detaining the five staffers and confiscating computers and documents, two senior local Kurdish officials said, speaking on condition of anonymity because of the sensitivity of the information. Irbil is a city in the Kurdish-controlled north, 350 kilometers from Baghdad. The report, which first appeared on Iraq state television, also was confirmed by a Shi'ite official in the capital, who declined to be named for the same reason. The US military had no immediate comment.
