Burkina Faso strongman Lieutenant-Colonel Paul-Henri Sandaogo Damiba was inaugurated as president on Wednesday, just over three weeks after he led a coup to topple elected head of state Roch Marc Christian Kabore.
In a televised ceremony, Damiba swore an oath before the country's top constitutional body to "preserve, respect, uphold and defend the Constitution", the nation's laws and a "fundamental act" of key decisions approved by the junta.
Damiba was dressed in camouflage uniform and a red beret, and wore a sash in the colours of Burkina's national flag.
The press, but no foreign representatives, attended the ceremony in a small room at the offices of the Constitutional Council.
On 24 January, Damiba, 41, led disgruntled officers to force out Kabore following public anger over his handling of a bloody jihadist insurgency.
Last week, the Constitutional Council formally determined that Damiba was president, head of state and supreme commander of the armed forces.
The move confirmed an announcement by the junta on 31 January that Damiba would be appointed to those roles for a transitional period, and be assisted by two vice presidents.
Burkina Faso is one of the world's poorest countries and one of the most volatile in Africa.
The landlocked Sahel state has experienced repeated coups since gaining independence from France in 1960.
Since the first jihadist attacks in 2015, more than 2,000 people have died, according to an AFP tally, while the country's emergencies agency says more than 1.5 million people have fled their homes.
The ceremony observed a minute's silence for the victims.
Damiba paid tribute to "the Burkinabe people, who have been enduring the scars of terrorism for more than six years" and called for "collective awareness about the effort and sacrifice" that were needed for the fight.
The junta suspended the constitution immediately on taking power on 24 January, but later reversed this in the face of pressure from neighbours in West Africa demanding a return to civilian rule.
The military authorities have promised to re-establish "constitutional order" within a "reasonable time" but the issue of a date for elections remains unsettled.
On 5 February, the junta announced that a 15-member commission would be tasked with "drawing up a draft charter and agenda, together with a proposal for the duration of the transition period."
Burkina was suspended on 3 February from the West African bloc ECOWAS, the 15-nation Economic Community of West African States.
But ECOWAS envoys came back with positive news from talks with the junta.
The bloc decided against punishing Burkina with further sanctions -- unlike coup-hit Guinea and Mali, which have been hit with border closures, an embargo on trade and financial transactions and sanctions against individuals for perceived foot-dragging over holding elections.
Instead, ECOWAS called for "the speedy creation of a reasonable timetable" for the return to civilian rule.

"At these difficult moments, our country has not been abandoned by its partners," Damiba said on Wednesday.
"Burkina Faso reiterates its readiness to work in full sovereignty with all partners in mutual respect."
On 31 January, Burkina was also suspended by the African Union "until the effective restoration of constitutional order."
The UN Security Council on 9 February expressed "serious concern" over the country's "unconstitutional change of government," but chose not to describe it as a military coup or even condemn it outright.
Damiba has had first-hand experience of the jihadist insurgency.
Before seizing power, he was commander of the 3rd Military Region, which covers eastern Burkina Faso -- one of the worst-hit areas.
A military source, speaking after the coup, described Damiba as "a tough commander who has been on the front line with his men".
Before the coup, Damiba criticised prevailing strategies to fight the jihadists, publishing a book last June called "West African Armies and Terrorism: Uncertain Answers?"
