Deposed dictator Masie Nguema Biyogo Negue Ndong and six former aides were sentenced to death today, and informed sources said they promptly were shot.

There was no immediate official confirmation that the executions had been carried out, but the sources said that seven were sent before firing squads at Malabo's notorious Blabich Prison within hours after the close of a four-day trial in which Masie Nguema was convicted of a number of crimes including genocide.

Masie Nguema, 57, was overthrown in a bloodless Army coup Aug. 3. He was captured 10 days later in the jungle of this former Spanish colony in Western Africa.

During an 11-year reign of terror, he acquired a reputation as one of Agrica's most ruthless dictators.

Tens of thousands of Equatorial Guinea's citizens were put to death during his rule as "president for life," and more than half the population of 300,000 fled from a country plunged into economic ruin, according to officials.

Masie Nguema was found guilty by a mixed civilian-military tribunal of genocide, participation in the murders of more than 100 Guineans, treason, systematic human rights violations and embezzlement of public funds.

The six aides who reportedly also were executed included a former vice president, Masie Nguema's bodyguard and three prison officers.The aides testified during the trial in an attempt to save their lives.

Equatorial Guinea is a 10,000-square-mile nation that under Masie Nguema became one of the Soviet Union's closest allies in Africa. His rule shattered the country's economy as he spent lavishly on palaces and other symbols of power while exports of the main cash crop, cocoa, steadily declined.
