The West African nation of Guinea-Bissau has been plunged into fresh political turmoil after the president sacked the government in a row with the prime minister.
The move came after President Jose Mario Vaz said in a broadcast to the nation late on Wednesday there was a "crisis" in relations with the prime minister that were undermining the functioning of government, raising fears of instability.
"The government headed by Prime Minister Domingos Simoes Pereira has been dissolved," a presidential decree said bluntly.
Despite concerns about the potential fallout from the crisis, life on Bissau streets carried on as usual, with no extra deployment of security forces, an AFP journalist said.
The army, quick to intervene in past political disputes in the coup-prone former Portuguese colony, remained in their barracks.
The 16-member government took office only in July 2014, two months after Vaz became Guinea-Bissau's first elected civilian leader since the army mutinied in 2012.
Vaz and Pereira are both members of the African Party for the Independence of Guinea and Cape Verde (PAIGC), which fought for independence from Portugal, won in 1974.
The party, which has a slender majority in the national assembly with 57 members of parliament out of 102, had been expected to meet at executive level on Thursday to consider naming a new prime minister, according to sources in the PAIGC, which is led by Pereira.
"It is public knowledge that there is a crisis undermining the proper working of institutions," Vaz said in the broadcast.
He said efforts at reconciliation between himself and Pereira failed.
"Even if all members of the government were dismissed from their posts, a cabinet reshuffle would not solve the crisis of confidence in the state leadership," he said.
Vaz said his dispute with Pereira arose from a number of issues including the appointment of a new armed forces chief, a post of key influence in the small nation ill-famed as a hub in drug trafficking between South America and Europe.
Since gaining independence in 1974, Guinea-Bissau's army and state have remained in constant conflict, and no president has completed a full term in office.
Three have been overthrown and one assassinated.
The country has undergone nine coups or attempted coups since 1980.
State of alert
In March 2009, Joao Bernardo "Nino" Vieira, who had led the country on and off since 1980, was assassinated by soldiers in apparent revenge for the killing of the then army chief.
"For two weeks, we have been in a state of alert, but confined to barracks," a senior military source told AFP.
He said army chief Biague Namtam, who was appointed in September, has "asked us to stay out of the political arena".
Vazalso raised the closure of the border with Guinea over an Ebola outbreak and cited problems of corruption and nepotism, a lack of transparency in public procurement and alleged obstruction of the judiciary.
Last week, Pereira had announced that his government would likely be dissolved due to differences of opinion with Vaz.
At a press conference on Thursday, he rejected Vaz's allegations against him and said he would use "all legal means" to once again lead the government.
"If the president asks the PAIGC to propose the name of the future prime minister, it will be me," he said.
The European Union has said the 2014 elections had brought the country "back on a path of democratic governance" and warned that the recent developments put at risk "the positive dynamics of reconstruction and democratic consolidation".
"All the democratic forces and institutions in Guinea Bissau need to work together now to overcome differences," it said.
The stability ushered in by last year's election led the EU to pledge 160m euros ($175m) in aid in March to bolster democracy and accelerate economic recovery.
And in May, the International Monetary Fund also praised the country's progress on economic reform, saying it had become eligible for a $23.9m loan.
The 2012 military coup brought chaos to a country already in the grip of powerful cocaine cartels and beset by political violence.
US drug enforcement officials see the country as a "narco-state" and several senior military officials have been charged by the US with drug trafficking.
