Protected by a dozen security guards and a metal detector, a controversial advisory panel to the Tokyo governor ended its final session Tuesday on a planned memorial hall for victims of U.S. air raids during World War II.

About 200 citizens had gathered at the No. 2 building of the Tokyo Metropolitan Government's head office in Shinjuku for the final session, with some shouting upon its close, "We oppose (plans for) the peace hall!"

The planned war museum has met with opposition from some politicians and scholars who argue that the draft for its permanent exhibits is based on a "masochistic view of history."
