OUAGADOUGOU, Burkina Faso (AP) — More than a dozen mutinous soldiers declared Monday on state television that a military junta now controls Burkina Faso after they detained the democratically elected president following a day of gunbattles in the capital.

The military coup is the third of its kind in West Africa in the last 18 months, creating upheaval in some of the countries hardest hit by Islamic extremist attacks.

Capt. Sidsore Kaber Ouedraogo said the Patriotic Movement for Safeguarding and Restoration “has decided to assume its responsibilities before history.” The soldiers were putting an end to Kabore’s presidency because of the deteriorating security situation amid the deepening Islamic insurgency and the president’s inability to manage the crisis, he said.

It was not immediately known where President Roch Marc Christian Kabore was, and the junta spokesman said only that the coup had taken place “without any physical violence against those arrested, who are being held in a safe place, with respect for their dignity.”

A soldier in the mutiny, who spoke on condition of anonymity due to the sensitivity of situation, told The Associated Press that Kabore had submitted his resignation.

The new military regime said it had dissolved Burkina Faso’s constitution and National Assembly. The country’s borders also have been closed, and a curfew will be in effect from 9 p.m. to 5 a.m.

Ouedraogo said that the country’s new leaders would work to establish a calendar “acceptable to everyone” for holding new elections without giving further details.

The announcement on state broadcaster RTB capped a day of confusion over who was in control of Burkina Faso, once a bastion of stability in the region that has faced growing violence from Islamic extremists during Kabore’s time in power.

In a statement, Kabore’s political party accused the mutinous soldiers of trying to assassinate the president and another government minister and said the presidential palace in Ouagadougou remained surrounded by “heavily armed and hooded men.”

“The army’s coup is a signal of frustration and exasperation on the heels of a growing struggle to stem the threat of militants, cope with the degraded security structure, and an attempt to restore faith in the institution of the military,” said Laith Alkhouri, CEO of Intelonyx Intelligence Advisory, which provides intelligence analysis.

Gunfire erupted early Sunday when soldiers took control of a major military barracks in the capital, Ouagadougou. In response, civilians rallied in a show of support for the rebellion but were dispersed by security forces firing tear gas. On Monday, groups of people celebrated again in the streets of the capital after reports of Kabore’s capture.
