Drunk soldiers looted Mali's presidential palace hours after they declared a coup on Thursday, suspending the constitution and dissolving the institutions of one of the few established democracies in this troubled corner of Africa.

The whereabouts of the country's 63-year-old president Amadou Toumani Toure, who was just one month away from stepping down after a decade in office, could not be confirmed. The United States Embassy issued a statement dispelling rumors that he had sought refuge in their compound.

The scene in this normally serene capital was unsettling to those proud of Mali's history as one of the mature democracies in the region. Soldiers smelling of alcohol ripped flat-screen TVs, computer monitors, printers and photocopiers out of the presidential palace, carting them off in plain sight. Others in pickup trucks zoomed across the broad avenues, holding beer bottles in one hand and firing automatic weapons with the other.

The mutineers said they were overthrowing the government because of its mishandling of an ethnic Tuareg insurgency in the country's north that began in January. Tens of thousands of Malian civilians have been forced to flee. The soldiers sent to fight the separatists have been killed in large numbers, often after being sent to the battlefield with inadequate arms and food supplies, prompting fierce criticism of the government.

The coup began Wednesday, after young troops mutinied at a military camp near the capital. The rioting spread to a garrison thousands of kilometers (miles) away in the strategic northern town of Gao.

By evening, soldiers had surrounded the state television station in Bamako. At dawn on Thursday, some 20 soldiers huddled behind a table, facing the camera. They introduced themselves as the National Committee for the Reestablishment of Democracy and the Restoration of the State, known by its French acronym, CNRDR.

"The CNRDR representing all the elements of the armed forces, defensive forces and security forces has decided to assume its responsibilities and end the incompetent and disavowed regime of Amadou Toumani Toure," they said, reading from a statement. "The objective of the CNRDR does not in any way aim to confiscate power, and we solemnly swear to return power to a democratically elected president as soon as national unity and territorial integrity are established."

The soldiers said they intended to hand over power to an elected government, though they made no mention of the fact that elections were supposed to be held on April 29. More than a dozen candidates were expected to run. Toure was not going to run in the election, as he had already served the maximum two terms.

Criticism of the coup was swift. France said would suspend all government cooperation with Mali, except for aid. In Washington, State Department spokeswoman Victoria Nuland said: "The United States condemns the military seizure of power in Mali" and said the U.S. stands by Toure's legitimately elected government.

And the regional body representing countries in the region, the Economic Community of West African States, called the coup "reprehensible."

The coup is a major setback for Mali, a landlocked nation of 15.4 million which is dirt-poor but fiercely proud of its democratic credentials. The current president came to power himself in a 1991 coup, but was hailed for handing power to civilians. A decade later, he won the 2002 election and was re-elected in 2007. There was never any question that Toure — known by his initials ATT — would step down at the end of his term next month.

"The situation is grave for our democracy and our republican institutions," said Ali Nouhoum Diallo, the former president of Mali's National Assembly. "We cannot approve the seizing of power through force."

The last statement from the presidency came via Twitter from the government's official account. Late Wednesday, they said: "This is not a coup. It's just a mutiny."

But as the sound of heavy weapons rang out, the emboldened soldiers encircled the palace. Contacted by telephone, an officer at the palace who requested anonymity because he was not authorized to speak to the press said that the president's bodyguards had failed to fight the renegade soldiers when they burst in. They searched the grounds but could not find Toure, and there were conflicting reports Thursday about where he might be hiding.

The mutinous soldiers imposed a nationwide curfew, warning people to stay off the streets until further notice. A flight headed to Bamako was forced to U-turn in the air after the borders were closed. At noon, soldiers were still riding on scooters and in pickup trucks shooting in the air, and local media was reporting casualties from stray bullets.

The CNRDR again addressed Malians at midday Thursday, and coup spokesman Lt. Amadou Konare ordered soldiers to stop randomly shooting. He also asked that public employees to return to work on Tuesday morning. He said any unjustified absences would be considered an abandonment of service.

"We ask our civilian compatriots to stay calm at home and we ask our comrades in uniform who have not yet joined the CNRDR to do so without delay," said Konare, reading a communique on state television.

In recent years, the U.S. military has been helping train Malian troops in counterterrorism tactics to fight al-Qaida-linked militants who have established bases in Mali's northern desert, the same area that is now beset by a Tuareg uprising.

The Tuaregs, a traditionally nomadic people spread across the Sahara Desert, have risen up against the central government in Mali several times since the country's independence from France in 1960.

The newest rebellion launched in mid-January broke years of relative peace, and has been fueled by the return of Tuaregs from Libya who had fought in Moammar Gadhafi's army. Tens of thousands of refugees have spilled over into four of the countries neighboring Mali due to the uprising.
