Heraldo de Madrid - Ousted Guinea-Bissau president arrives in Brazzaville: Congolese sources

Meanwhile in the capital Bissau, the west African country's leading opposition party said its headquarters had been "invaded" by a "heavily armed militia", in the wake of the post-election coup that propelled the army to power.

The military took control of the Portuguese-speaking nation on Wednesday -- a day before the provisional results of national elections were due to be announced -- and Embalo initially left for neighbouring Senegal.

The true motives for the coup in Guinea-Bissau remain unclear, with speculation and conspiracy theories circulating -- including that the coup was carried out with Embalo's blessing.

"Embalo arrived in Brazzaville late in the morning on a private jet," a source close to the Congolese government said on condition of anonymity.

A presidency source said Embalo, who had claimed victory in the election, intended to remain in the country, which is also known as Congo-Brazzaville.

Embalo, 53, is rumoured to be close to Congolese President Denis Sassou Nguesso, and has visited the Republic of Congo many times.

After taking power on Wednesday, the officers in charge argued they had taken control to restore order, warning of a plot by the country's drug barons to destabilise Guinea-Bissau.

The opposition and some experts however suspect that Embalo, in power since 2020, orchestrated the takeover to halt the electoral process.

Those suspicions intensified when the junta named General Horta N'Tam, considered a close ally of the president, to head a transitional administration set to last a year.

On Saturday, the African Party for the Independence of Guinea and Cape Verde (PAIGC), Guinea-Bissau's powerful opposition party, said in a statement that its headquarters had been "illegally invaded by heavily armed militia groups" in Bissau.

Elsewhere in the capital, minor clashes broke out on Saturday between young people and law enforcement officers in a suburb not far from the headquarters of Fernando Dias, who ran against Embalo and was arrested on the day of the coup.

Some political researchers say a high-level turf war to control illegal drug smuggling networks may have also played a part in Guinea-Bissau's instability.

Crippling poverty, chaotic administration and political tumult have made Guinea-Bissau a fertile ground for corruption and drug smuggling.

It is a key transit point for Latin American cocaine destined for Europe to the point that some analysts have dubbed it a "narco-state".

Senior politicians and military brass are suspected of implication in the illicit hard drugs trade.

Sandwiched between Senegal and Guinea, Guinea-Bissau had already undergone four coups and a host of attempted takeovers since its independence from Portugal in 1974.

Among the world's poorest countries, it has now joined the likes of Burkina Faso, Mali, Madagascar, Niger and Sudan on the list of states suspended from the African Union following coups.
