Capt. Moussa "Dadis" Camara said on state television late Tuesday that he had banned all gatherings and demonstrations. He blamed the opposition for acting irresponsibly in Monday's demonstration and called for an inquiry. He said the government would pay the families of the wounded and dead. He also warned religious leaders, politicians and the media against inciting violence.

Flags fluttered at half-staff in the capital's quiet streets Wednesday morning. A human rights group says 157 people were killed and more than 1,000 wounded in the protest against Camara. Witnesses say soldiers raped women in the streets.

Hospitals were flooded with patients on Tuesday and the death toll rose through the day after presidential guard troops shot at 50,000 people at the main football stadium, shattering hopes that this West African country was shedding the yoke of dictatorship.

Some of those at the rally, upset that a military officer who seized power in a December coup might run for president in January elections, had chanted: "We want true democracy."

Camara's presidential guard opened fire with live ammunition, scattering panicked demonstrators who left scores of dead behind. Opposition politician Mutarr Diallo said he witnessed soldiers raping women with rifle butts.

The Interior Ministry released a statement late Tuesday saying the government would open an investigation to find out who ordered the soldiers to fire on people with live ammunition. However, the statement said 57 people had been killed and only four of them died from bullets. The rest were trampled or died of asphyxiation, it said.

The statement also said that the president expressed his condolences for the families who lost loved ones.

Local journalists said that Camara, who was not present at the stadium Monday, visited the wounded at two hospitals in Guinea's capital on Tuesday. Earlier he had told Radio France International that the violence was beyond his control.

"Those people who committed those atrocities were uncontrollable elements in the military," he told Radio France International on Monday night. "Even I, as head of state in this very tense situation, cannot claim to be able to control those elements in the military."

Human rights groups demanded that those responsible be made accountable.

"Guinea's leaders should order an immediate end to attacks on demonstrators and bring to justice those responsible for the bloodshed," said Corinne Dufka of Human Rights Watch.

Dr. Chierno Maadjou with the Guinean Organization for Defense of Human Rights said 157 people were killed and more than 1,200 wounded.

An Associated Press reporter saw wounded patients crowded into the large Donka Hospital, some with bullet wounds, others who appeared to have been beaten.

Guinea's mineral-rich soil had been plundered by two consecutive dictatorships before Camara seized control of the country a day after President Lansana Conte, who had ruled for nearly a quarter-century, died on Dec. 22. Camara initially was embraced by Guineans, thousands of whom lined the streets to applaud him as he rode through the capital on the back of a flatbed military truck.

But since then, tensions have risen amid rumors that Camara may run in presidential elections scheduled for Jan. 31. He initially indicated that he would not run but said recently he has the right to do so if he chooses.

Demonstrations against Camara have grown in recent weeks but the reaction by security forces had been comparatively moderate. Late last month, police fired tear gas to break up a demonstration in the capital, and last Thursday tens of thousands of residents in a town north of Conakry took to the streets with no serious incidents.

The African Union, the European Union and the government of neighboring Senegal denounced Monday's bloodshed. The AU already had suspended Guinea's membership after Camara seized power. France's foreign minister said his country is suspending military cooperation with its former colony.

Eyewitnesses told New York-based Human Rights Watch that security forces stripped female protesters and raped them in the streets. The rights group, citing eyewitness reports, said soldiers on Monday also stabbed protesters with knives and bayonets.

Hardly anyone had heard of Camara, an army captain in his 40s, until his men broke down the glass doors of the state TV station on Dec. 23. He announced that the constitution had been dissolved and that the country was under the rule of a military junta. Many began to question his tactics when he authorized raids on the homes of well-known members of the dead president's inner circle. Camara claimed the raids were intended to recoup money and property stolen from the state, but many complained of heavy-handed tactics.

The military junta also put top government officials on TV, where they detailed their roles in a lucrative international cocaine trade in Guinea. Guinea and other West African countries in recent years emerged as key transshipment points for cocaine bound from South America to Europe.

Camara's arrests of corrupt officials have won him admiration, but he has been criticized for his love of the spotlight and his insistence on broadcasting rambling, multi-hour tirades. Camara generally sleeps all day only to emerge at night, and has a waiting room adorned with 6-foot-tall portraits of himself.

Since winning independence half a century ago from France, Guinea has been pillaged by its ruling elite. Its 10 million people are among the world's poorest, even though its soil has diamonds, gold, iron and half the world's reserves of the raw material used to make aluminum.
