MADRID (AP) — Three members of an international committee that oversaw a partial disarmament by Basque separatist group ETA have appeared in court to answer questions before an investigating judge.

Judge Ismael Moreno summoned them to Spain’s National Court after committee spokesman Ram Manikkalingam said Friday that ETA had placed a small quantity of weapons out of use in what is viewed as a first step toward an unconditional total disarmament.
