BUENOS AIRES — A court in Argentina on Thursday convicted two former senior government officials for obstructing the investigation into the deadly 1994 terrorist attack against a Jewish community center in Buenos Aires, the first time any top officials have been held criminally accountable in the case.

The suicide bombing, the worst terrorist assault in the country’s history and one of the deadliest anti-Semitic attacks since World War II, left 85 people dead and more than 300 wounded.

In all, the court sentenced eight people accused of a cover-up, among them a former federal judge and a former head of the intelligence services, but it acquitted five others, including the highest-profile defendant: former President Carlos Menem.
